Solving Quadratic Equations by Factoring

Factor

 $x^2+11x+24$  

• (x + 1)(x + 24)

• (x + 2)((x + 12)

• (x + 3)(x + 8)

• (x + 4)(x + 6)

Solve

 $\left(x\ +\ 3\right)\left(x\ +\ 8\right)=0$  

• x = 3 and x = 8

• x = -3 and x = 8

• x = 3 and x = -8

• x = -3 and x = -8

Factor

 $x^2+4x-32$  

• (x + 2)(x - 16)

• (x - 2)((x + 16)

• (x + 4)(x - 8)

• (x - 4)(x + 8)

Solve

 $\left(x\ -\ 4\right)\left(x\ +\ 8\right)=0$  

• x = 4 and x = 8

• x = -4 and x = 8

• x = 4 and x = -8

• x = -4 and x = -8

Factor

 $x^2-5x-36$  

• (x + 2)(x - 18)

• (x + 3)(x - 12)

• (x + 4)(x - 9)

• (x + 6)(x - 6)

Solve

 $\left(x\ +\ 4\right)\left(x\ -\ 9\right)=0$  

• x = 4 and x = 9

• x = -4 and x = 9

• x = 4 and x = -9

• x = -4 and x = -9

Factor

 $x^2-26x+48$  

• (x - 2)(x - 24)

• (x - 3)(x - 16)

• (x - 4)(x - 12)

• (x - 6)(x - 8)

Solve

 $\left(x\ -\ 2\right)\left(x\ -\ 24\right)=0$  

• x = 2 and x = 24

• x = -2 and x = 24

• x = 2 and x = -24

• x = -2 and x = -24
