Lesson Steps

Steps	Problem	Solution
1	Find the product of polynomials.	\$ (2x − 1)^2 \$
2	Applying formula \$ (a-b)^2 = a^2 - 2ab + b^2 \$	\$ (2x)^2 - 2(2x)(1) + (1)^2 \$
3	After simplification	\$ 4x^2 - 4x + 1 \$
4	Answer	C = \$4x^2 - 4x + 1 \$

Steps

Problem

Solution

Find the product of polynomials.

\$ (2x − 1)^2 \$

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

\$ (2x)^2 - 2(2x)(1) + (1)^2 \$

After simplification

\$ 4x^2 - 4x + 1 \$

Answer

C = \$4x^2 - 4x + 1 \$
