Answer:
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
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
