What is the sum of the polynomials?
11x2 – 5
+
X+4.

10x²9
11x^2-x-9
11x²+x-1
12x²-1​

Respuesta :

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
