Combine like terms 4x3-5x2+4x2-7x3-2x+3x2

=-3 +2  -2x

Step by step explanation

the equation is

4 -7 -5 +4 +3 -2x

we just have to simplify the equation

for this we will add and subtract the numbers with same powers i.e we will ad powers of x raise to power 3 with another x raise to power three

and similarly for other powers

=-3 +2  -2x

-18 degrees is the answer : )
