Question

Subtract the problem below.

Answer 1

C) 3x squared - 13x + 7

Explanation:

To subtract this problem you need to combine like terms

6x squared - 3x squared = 3x squared

-5x - 8x = -13

3 - -4 = 7

Since you combined the like terms put it back into an expression

3x squared - 13x + 7

Since the 13 is negative it becomes a subtraction sign in this expression.

The 7 is positive so it becomes an addition sign.

Answer 2

C. 3x^2 -13x + 7
