Question

Find value of k and h if (x+1) and (x+2) are factors of x^3 + hx^2 + kx + 4

Answer 1

since (x+1) and (x+2) are factors, x = -1 and x = -2 are zeroes

Answer 2

plug them in
x^3 + hx^2 + kx + 4 = 0

Answer 3

you would get 2 equations, solve them for h and k

Answer 4

Thank get the idea now
