Question

(2x + 2x + 3) - (x2+2x+1) =O A. x2 + 2O B. x2 + 4x + 2O c. x²+4O D. x2 + 4x + 4

Answer 1

We are given the following difference of polynomials:

$(2x^2+2x+3)-(x^2+2x+1)$

Let's group tohether similar terms in order to solve it, and remember that the "-" sign affects every element inside the parentheses. With this, we rewrite the opperation as follows:

$(2x^2-x^2)+(2x-2x)+(3-1)=x^2+0+2=x^2+2$

And so, the result is

$x^2+2$
