Answer:
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
