Divide.

(10x^3 + 5x^2 - 4x) : x

10x^2+5x-4

Step-by-step explanation:

(10x^3+5x^2-4x) / x

Notes that in 10x^3+5x^2-4x every part of this sum has x. So we can do-

10x^3+5x^2-4x = x (10x^2+5x-4)

Now if we divide with x we get:

x (10x^2+5x-4) / x = 10x^2+5x-4

10x^2+5x-4

Step-by-step explanation:

Rewrite the division as a fraction.

Factor x out of 10x^3+5x^2-4x.

Cancel the common factor of x.

Thus 10x^2+5x-4
