Question

Square the binomial using Binomial Squares Pattern (simplify) ( x + 6/7)^2

Answer 1

In order to square this binomial, we can use the binomial square pattern below:

$(a+b)^2=a^2+2ab+b^2$

So we have:

$\begin{gathered} (x+\frac{6}{7})^2=x^2+2\cdot x\cdot\frac{6}{7}+(\frac{6}{7})^2 \\ =x^2+\frac{12}{7}x+\frac{36}{49} \end{gathered}$
