Solution 1

To find the value of m, we can use the Remainder Theorem which states that the remainder of a polynomial f(x) divided by (x-a) is equal to f(a).

In this case, our polynomial is f(x) = x^3 + mx^2 + 7x - 6 and we are dividing by x + 2, so a = -2.

Substituting a = -2 into the polynomial gives us the Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
