Can x 2 4x 4 be factored?
So the factored form is (x+2)(x+2) or (x+2)2 .
What is the factored form of 2x 4?
So, Factors of 2x+4 is 0 and -2.
What are the roots of x² 2x 4 0?
Answer: The quadratic equations x2 + 2x – 4 = 0 and x2 – 2x – 4 = 0 have the real solutions. If the roots are real then the equation has the real roots, if the roots are imaginary, then the equation has no real roots. Here, we have complex roots.
Can x 2 +4 be simplified?
(2) Can the formula √x2+4 be simplified? No. For starters (x2+4)>0 for all x∈R , so it has no linear factors with real coefficients.
Is x 2 4x 4 a perfect square trinomial?

What is the factored form of X² 2x?
Explanation. Yes, the solution is x(x-2).
Which expression is a factor?
factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.
What type of equation is x² 2x 4 0?
quadratic equations
Here, we have real roots. Therefore, the quadratic equations x2 + 2x – 4 = 0 and x2 – 2x – 4 = 0 have the real solutions.
What is the solution set for this quadratic equation x2 − 2x − 4 0?
Two solutions were found : x =(2-√20)/2=1-√ 5 = -1.236.
Can you factor x2 2x 2?
This is not factorable normally. We can see this since x2−2x+1 is a perfect square, so it touches the x-axis at a single root.
Is x 2 4x 2 a perfect square trinomial?
The number that should be added to the expression x2+4x to change it into a perfect square trinomial is 4.
