Question from Em:

One root of the equation 2x^2 + bx - 24 = 0 is -8. What are the possible values of b and the other root?

Hi Em,

I suggest that you use the expressions for the sum of the roots and the product of the roots of a quadratic equation as well as the fact that one of the roots is -8 to solve this problem.

Write back if you need further assistance,
