(4x^2 + 2x – 3) + (x^2 – x + 9)

= 4x^2 + 2x – 3 + x^2 – x + 9

= (4x^2 + x^2) + (2x - x) + (9 - 3)

= 5x^2 + x + 6

= 4x^2 + 2x – 3 + x^2 – x + 9

= (4x^2 + x^2) + (2x - x) + (9 - 3)

= 5x^2 + x + 6

Add the following polynomials: (4x^2 + 2x – 3) + (x^2 – x + 9)
a. 5x^2+x+6
b. 4x^2+x+6
c. 5x^2+x+5
d. 4x^2+x+5
**Weegy:** the product (x + 1)(x + 4) will be-
(x + 1)(x + 4)= x^2+4x+x+4 = x^2+5x+4
So the answer will be option A- x^2+5x+4 **User:** Add the following polynomials: (4x^2 + 2x – 3) + (x^2 – x + 9)
