Lesson Steps

Steps	Problem	Solution
1	Find the product of polynomials.	\$ (3x + 5)^2 \$
2	Applying formula \$ (a+b)^2 = a^2 + 2ab + b^2 \$	\$ (3x)^2 + 2(3x)(5) + (5)^2 \$
3	After simplification	\$ 9x^2 + 30x + 25 \$
4	Answer	D = \$9x^2 + 30x + 25\$

Steps

Problem

Solution

Find the product of polynomials.

\$ (3x + 5)^2 \$

Applying formula \$ (a+b)^2 = a^2 + 2ab + b^2 \$

\$ (3x)^2 + 2(3x)(5) + (5)^2 \$

After simplification

\$ 9x^2 + 30x + 25 \$

Answer

D = \$9x^2 + 30x + 25\$
