###### Not exactly what you’re looking for?
Francisco Proctor
first start with the $\left(7x-2{\right)}^{2}$
$\left(7x-2\right)\left(7x-2\right)=49{x}^{2}-14x-14x+4$
combinelike terms
$49{x}^{2}-28x+4$ <----once you have this just add it to(7x - 2)
$49{x}^{2}-28x+4+7x-2$ <-----again combine like terms
$49{x}^{2}-21x+2$ <----so this is your final answer
