(3x^2 + x^2 - 22x - 25) ÷ (x - 2)

Since 3x^2 and x^2 are like terms, you need to add them together since the operation between them is addition.

3x^2 + x^2 = 4x^2

(4x^2 -22x -25) ÷ (x - 2)
Perform synthetic division or long-method division to get the answer. Unfortunately, I cannot show you how I solved your problem here.

The final answer should be 4x-14 and the remainder will be -53
