Question

Subtract the polynomials (3x^7-2x+5)-(x^7+3)

Answer 1

Answer: 2x^7-2x+2

Explanation:

Find the sum of the combinable terms

3x^7 - x^7 = 2x^7

Since there is no other term for -2x to be combined with, it remains the same.

5 - 3 = 2

Take the individual sums and combine them into one polynomial

2x^7 - 2x + 2

Answer 2

2x^7 - 2x + 2
