Write down the sum and product of the roots of the following quadratic polynomials:

Question

(a) 3x^2 - 6x - 7

(b) 3x^2 + 6x + 7

Answer 1

To talk about "roots" you need equations, you don't have any.

anyway....
for 3x^2 - 6x - 7 = 0 , the sum of the roots is 6/2 or 3
and the product of the roots is -7/3
