Step-by-step explanation:

Let's simplify step-by-step.

−x2+2x−2x2−3x+4+x2

=−x2+2x+−2x2+−3x+4+x2

Combine Like Terms:

=−x2+2x+−2x2+−3x+4+x2

=(−x2+−2x2+x2)+(2x+−3x)+(4)

=−2x2+−x+4

Answer:

=−2x2−x+4

How to divide fractions
Anna [14]

First leave the first fraction alone.

Then turn the division sign into a multiplication sign.

Flip the second fraction over ( find its reciprocal ).

Multiply the numerators of the two fractions together. This result will be the numerator ( the top part ) of your answer.

Multiply the denominators of the two fractions together. The result will be the denominator ( the bottom part ) of your answer.

Then simplify your fraction by reducing it to the simplest terms.
