Question

Subtract these polynomials.

(3x^2-2x+5)-(x^2+3)

Answer 1

2x²-2x+2

Explanation:

To subtract polynomials, combine like terms:

3x²-x² = 2x²

-2x has no like terms; that leaves -2x

5-3 = 2

This gives us

2x²-2x+2

Answer 2

2x^2-2x+2. make sure you distribute the ‘negative’ to the second part. so distribute the negative to a positive would be negative, but with a negative it would become positive (so add the terms)
