QUESTION:solve for the quadratic equation of each roots

-3 and 7

ANSWER:

If you are given that the roots are -3 and -7, those are your x intercepts.

since we are trying to reach a quadratic equation we are looking for two algebraic expressions that are factors. So I will move the -3 and -7 to the left side of each equation through opposite operations.x+3=0 and x+7=0 Since both are set to zero we can use the zero product rule of ab=0.

Since both are set to zero we can use the zero product rule of ab=0.

(x+3)(x+7)=0.FOIL it

x^2+7x+3x+21=0.simplify

x2+10x+21=0.Answer
