Question

the sum of polynomials 6x^3+8x^2-2x+4and 10x^3+x^2+11x+9is

Answer 1

6x^3+10x^3+8x^2+x^2-2x+11x+4+9

16x^3+9x^2+9x+13

Answer 2

6x³+8x²-2x+4+10x³+x²+11x+9
Combining like terms
6x³+10x³+8x²+x²-2x+11x+4+9
=16x³+9x²+9x+13. As a result, the sum of polynomials 6x³+8x²-2x+4 and 10x³+x²+11x+9 is 16x³+9x²+9x+13. Hope it help!
