The sum of the polynomials 6x3 + 8x2 – 2x + 4 and 10x3 + x2 + 11x + 9 is

16x^2 + 9x^2 + 9x + 13.

Step-by-step explanation:

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

Bringing like terms together:

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

= 16x^2 + 9x^2 + 9x + 13.  (answer).

step-by-step explanation:

it's the only multiple of both and the least

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
