## How do you solve a quadratic equation by factoring?

To solve an quadratic equation using factoring :

- 1 . Transform the equation using standard form in which one side is zero.
- 2 . Factor the non-zero side.
- 3 . Set each factor to zero (Remember: a product of factors is zero if and only if one or more of the factors is zero).
- 4 . Solve each resulting equation.

**What does it mean to solve by graphing?**

A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system.

**How do you graph quadratic equations?**

Graph a quadratic equation in two variables.

- Write the quadratic equation with. on one side.
- Determine whether the parabola opens upward or downward.
- Find the axis of symmetry.
- Find the vertex.
- Find the y-intercept.
- Find the x-intercepts.
- Graph the parabola.

### Can all quadratic equations be solved by graphing?

Don’t be fooled: Not all quadratic equations can be solved by factoring. For example, x2 – 3x = 3 is not solvable with this method. One way to solve quadratic equations is by completing the square; still another method is to graph the solution (a quadratic graph forms a parabolaâ€”a U-shaped line seen on the graph).

**Which is the correct step by step procedure in solving equation by factoring?**

Steps for Solving Quadratic Equations by Factoring

- Write the equation in standard form:
- Factor completely.
- Apply the Zero Product Rule , by setting each factor containing a variable to zero. If ab = 0, then a = 0 or b = 0.
- Solve the linear equations in step 3.
- Check.

**What is quadratic graph?**

Graphs. A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. Parabolas may open upward or downward and vary in “width” or “steepness”, but they all have the same basic “U” shape.

#### How do you solve by graphing?

To solve a system of linear equations by graphing.

- Graph the first equation.
- Graph the second equation on the same rectangular coordinate system.
- Determine whether the lines intersect, are parallel, or are the same line.
- Identify the solution to the system. If the lines intersect, identify the point of intersection.
