Simplify the following polynomial expression

(3x^2-x--4x-2)+(x+3)(x+2)

The polynomial simplifies to an expression that is a - x^2+8x+1 with a degree of 2.

Step-by-step explanation:

(3x^2-x-7)-(5x^2-4x-2)+(x+3)(x+2)

By MDAS, we will start with multiplication using the foil method

(3x^2-x-7)-(5x^2-4x-2)+(x^2+2x+3x+6)

Combine like terms in each parenthesis

(3x^2-x-7)-(5x^2-4x-2)+(x^2+5x+6)

Distribute the negative sign

3x^2- x- 7- 5x^2+ 4x + 2+x^2 + 5x +6, combine like terms

4x^2-5x^2+8x+1

-x^2+8x+1.
