$(7x-2{)}^{2}+(7x-2)$

$(49{x}^{2}-14x-14x+4)+(7x-2)$

$(49{x}^{2}-28x+4)+(7x-2)$

$49{x}^{2}-28x+4+7x-2$

$49{x}^{2}-21x+2$

$(49{x}^{2}-14x-14x+4)+(7x-2)$

$(49{x}^{2}-28x+4)+(7x-2)$

$49{x}^{2}-28x+4+7x-2$

$49{x}^{2}-21x+2$

first start with the $(7x-2{)}^{2}$

$(7x-2)(7x-2)=49{x}^{2}-14x-14x+4$

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

$(7x-2)(7x-2)=49{x}^{2}-14x-14x+4$

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
