To subtract − 10 x + 3 −10x+3 from − 7 x 2 + 5 x + 10 −7x^2+5x+10, we need to subtract each term in − 10 x + 3 −10x+3 from each term in − 7 x 2 + 5 x + 10 −7x^2+5x+10.
So,
-7x^2 + 5x + 10 - (-10x + 3)
= -7x^2 + 5x + 10 + 10x - 3
= -7x^2 + 15x + 7
Therefore, the result of subtracting − 10 x + 3 −10x+3 from − 7 x 2 + 5 x + 10 −7x^2+5x+10 is -7x^2 + 15x + 7.
The result of subtracting -10x+3 from -7x^2+5x+10 is -7x^2 + 15x + 7.
However, if the expression is -7x^2 + 5x + 10 - (-10x + 3), then we have:
-7x^2 + 5x + 10 - (-10x + 3) = -7x^2 + 5x + 10 + 10x - 3 = -7x^2 + 15x + 7
Simplifying further, we can write -7x^2 + 15x + 7 as -2x - 14(when we factor out -7 from -7x^2 + 15x + 7). So, the answer can be written as -2x - 14.
