Answer:

x^3 - 7x^2 + 4x +30

Step-by-step explanation:

x times x^2= x^3           -5 times x^2 = -5x^2

x times -2x= -2x^2        -5 times -2x = 10x

x times -6 = -6x             -5 times -6 = 30

Combine like terms

(-5x^2 and -2x^2) = -7x^2

(10x - 6x) = 4x

Carry down the remaining (x^3 and 30)

x^3 - 7x^2 + 4x + 30
