Factoring and Operations of Polynomials

Find the sum.
(2x² + 5x - 7) + ( 3 - 4x² + 6x)

• 2x² + 3x +1

• -2x² - 11x -4

• 2x² + 5x -7

• -2x² + 11x -4

Find the difference. 
(3- 2x + 2x²) - (4x -5 +3x²)

• x_² + 6x + 8

• 2x² + 5x - 7

• -x² -6x + 8

• -2x² + 11x - 4

(x - 3)(x +10)

• x^2 - 7x + 13

• x^2 - 6x - 30

• x^2 + 7x - 30

• x^2 + 13x + 30
