What is the sum of the polynomials?

11x2 - 5

+

X+4.

10x²9

11x^2-x-9

11x²+x-1

12x²-1

11x2 + x - 1 because you add the squared variables, than the x to the power of 1 and then the constants

11x^{2}+x-1

Step-by-step explanation:

we have

(11x^{2} - 5) + (x+4)

we know that

The sum of a quadratic equation and a linear equation will be a quadratic equation

so

Combine like terms

(11x^{2}) + (x) + (-5+4)

11x^{2}+x-1
