Question

Use the grouping method to factor the polynomial below completly x^3+2x^2+3x+6

Answer 1

Explanation:

Use the distributive property twice.

(x^3 + 2x^2) + (3x + 6)

Now pull out the common factors.

x^2(x + 2) + 3(x + 2)

x + 2 is a common factor of the 2 expressions on either side of the isolated plus sign.

(x + 2) (x^2 + 3)
