Find the zeros of each quadratic function by factoring.

Set A

1.f(x)=5x^ 2 -5

4.f(x)=x^ 2 +4x+3

2.g(x)=2x^ 2 -12

5.g(x)=x^ 2 +5x+6

3.h(x)=3x^ 2 -27

Set B

Set C

1.f(x)=36x^ 2 -49

1.f(x)=x^ 2 -5x+6

2.g(x)=x^ 2 +3x+2

2.g(x)=x^ 2 +5x-14

3.h(x)=x^ 2 +7x+12

3.h(x)=x^ 2 -4x-21

4.f(x)=x^ 2 +5x-6

4.f(x)=2x^ 2 +x-1

5.g(x)=x^ 2 -x-12

5.g(x)=3x^ 2 +8x+
