Add the following polynomials: (x^2 – 4x – 3) + (x^2 – 3x – 7)
a. -2x^2-7x-10
b. 2x^2+7x-10
c. 2x^2-7x-10
d. 2x^2-7x+10
**Weegy:** (x2 ? 4x ? 3) + (x2 ? 3x ? 7)
= x^2 - 4x - 3 + x^2 - 3x - 7
= 2x^2 - 7x - 10 **User:** Add the following polynomials: (x2 – 4x – 3) + (x2 – 3x – 7)
-2x2-7x-10
2x2+7x-10
2x2-7x-10
2x2-7x+10
**Weegy:** 2x2-7x-10. (x2 – 4x – 3) + (x2 – 3x – 7) = 2x2-7x-10. (More)
