Question

Solve the square using the binomial squares pattern.

${\left(4y^3-2\right)}^2$

Step-by-Step Solution

Answer

The solution is $16y^6-16y^3+4$.

Step 1. Given information.

The given expression is ${\left(4y^3-2\right)}^2$.

Step 2. Simplify the given expression by using the binomial squares pattern a - b 2 = a 2 - 2 a b + b 2 .

Solve it as follows:

$$\begin{gathered} {\left(4y^3-2\right)}^2={\left(4y^3\right)}^2-2\times 4y^3\times 2+{\left(2\right)}^2 \\ \Rightarrow 16y^6-16y^3+4 \end{gathered}$$

Step 3. Binomial squares expression.

Hence, the binomial squares pattern are $16y^6-16y^3+4$.
