Use what you know about addition and subtraction of polynomials to find the missing term represented by the question mark in each equation. (–4x2 + 6x + 3) + (8x + 5 + ?) = 2x2 + 14x + 8

Respuesta :

Answer:

6x²

Step-by-step explanation:

Adding polynomials involves combining like terms.

We can see that 6x and 8x are combined to make 14x, and 3 and 5 are combined to make 8.

We also know that -4x² is combined with something to equal 2x².  To find the missing value, we subtract:

2x²-(-4x²) = 2x²+4x² = 6x²
