# What is the perfect square trinomial?

## What is the perfect square trinomial?

A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product. If the pattern does not fit for a particular trinomial, it is not a perfect square trinomial.

Which pair of binomials gives a product that is a perfect square trinomial?

Any time you take a binomial and multiply it to itself, you end up with a perfect square trinomial. For example, take the binomial (x + 2) and multiply it by itself (x + 2). The result is a perfect square trinomial.

How do you identify if a polynomial is a perfect square trinomial?

Multiply the roots of the first and third terms together. Compare to the middle terms with the result in step two. If the first and last terms are perfect squares, and the middle term’s coefficient is twice the product of the square roots of the first and last terms, then the expression is a perfect square trinomial.

### How do you teach perfect square Trinomials?

Recall that for a trinomial to be a perfect square trinomial, it must be in the form 𝑎 ± 2 𝑎 𝑏 + 𝑏   ; it can then be factored as ( 𝑎 ± 𝑏 )  . Here, we have a negative coefficient of the middle term, so the perfect square trinomial will be in the form 𝑎 − 2 𝑎 𝑏 + 𝑏   .

How do you know if an equation is a perfect square trinomial?

How do you solve trinomials step by step?

Now let’s factor the trinomial:

1. Step 1: Identify the values for b and c. In this example, b=6 and c=8.
2. Step 2: Find two numbers that ADD to b and MULTIPLY to c. This step can take a little bit of trial-and-error.
3. Step 3: Use the numbers you picked to write out the factors and check.

## Why do we need to follow the steps in factoring perfect square trinomials?

It’s important to recognize the form of perfect square trinomials so that we can easily factor them without going through the steps of factoring trinomials, which can be very time consuming. To factor a perfect square trinomial we need to be able to recognize perfect square factors.

How do you identify a trinomial?

A monomial is a polynomial with exactly one term. A binomial has exactly two terms, and a trinomial has exactly three terms. There are no special names for polynomials with more than three terms.

What are the rules of trinomials?

The rules are as follows: If all terms of the trinomial are positive, then all terms of the binomials will be positive. If the last term of the trinomial is negative but the middle term and the first term are positive, then one term of the binomial will be negative and the other will be positive.

### What fractions are a perfect square?

– For example: ( 12 / 16) 2 – 12 and 16 can both be divided by 4. 12/4 = 3 and 16/4 = 4; therefore, 12 / 16 reduces to 3 / 4. – Now, you will square the fraction 3 / 4. – ( 3 / 4) 2 = 9 / 16, which cannot be reduced. – To prove this, let’s square the original fraction without reducing: ( 12 / 16) 2 = ( 12 x 12 / 16 x 16) = ( 144 / 256) (

How do I calculate a perfect square?

9 is a perfect square because it can be expressed as 3*3 (product of two equal integers)

• 16 is a perfect square because it can be expressed as 4*4 (product of two equal integers)
• 8 is not a perfect square because it can not be expressed it as product of two equal integers
• How do you factor out a perfect square?

Memorize a few perfect squares. Squaring a number,or multiplying it by itself,creates a perfect square.

• Find the square root of a perfect square. If you recognize a perfect square under a square root symbol,you can immediately turn it into its square root and
• Factor numbers into perfect squares.
• Factor a number with more than one perfect square.
• ## How do you solve a perfect square?

Factor the number completely. An easy way to factor a number is by using a factor tree.

• Match up pairs of the same number. Any numbers with a partner are perfect squares,and you can take the square root of these numbers.
• Numbers without a partner remain under the square root.
