Question

Find the product of (x + 3)^2

Answer 1

x^(2)+6x+9 also x=-3

Explanation:

Answer 2

(x+3)² = (x+3)(x+3)

When we distribute polynomials, we have to make sure each term mutliplies to all of the terms in the other polynomial.

x(x+3) + 3(x+3)

x² + 3x + 3x + 9

x² + 6x + 9

Methods such as FOIL (first, outside, inside, last) and creating a table can help you with this.
