answer -3x + 14
(7x^2 - x + 1) - (2x^2 - x - 3) - (5x^2 + 3x - 10)
remove ( ) by distributing the subtraction
7x^2 - x + 1 - 2x^2 + x + 3 - 5 x^2 - 3x + 10
gather like terms
7x^2 - 2x^2 - 5 x^2 - x + x - 3x + 1 + 3 + 10
combine like terms
0x^2 -3x + 14 which is -3x + 14

1. remove the paraenthesis from the equation
7x^2 - x + 1 -2x^2 + x + 3 - 5x^2 - 3x + 10
2. Combine like terms
0x^2 -3x + 14 ----> -3x + 14
Thanks all there is to it!

7x^2 - 2x^2 - 5x^2 = 0
-x + x - 3x = -3x
1 + 3 + 10 = 14
-3x + 14

=(7x^2 - x + 1) - (2x^2 - x - 3) - (5x^2 + 3x - 10)
=7x^2-x+1-2x^2+x+3-5x^2-3x+10
=-3x+14
