HOW TO GET SOLUTIONS
After factoring, set each factor equal to zero and solve.
The values that make each factor equal zero are the solutions.

Steps to solve a quadratic by factoring:
1. Set the equation equal to zero. ax2+bx+c=0
2. Factor. (x +  )(x + ) = 0
3. Find the value that makes each factor equal zero.

Question 4

Find the solutions.

a = _______

Question 5
