This week we learned how to solve a quadratic equation using factoring.
In order to solve the equation the zero product law must be used.
a*b=0, so either a=0 or b=0.
both sides if the equals sign must be equal.
for example: 8(x+2)(x-7)=0
a quadratic equation has two possible answers. If you plug either of them into the equation, it should work.
to solve any quadratic equation, the product must be 0. The equation cannot work without it.
