Answer 1

hello here is your answer by Sujeet yaduvanshi ☝☝☝☝

We know that Formula

(a-b)²


so broken this form

(x-7)²

x²-2.x.7+7²

x²-14x+49


Note-. . it's meant multiply

Answer 2

Hey there!

We know that,

( a - b) ² = a² + b² - 2ab .

( a - b) ( a - b)
= a² - ab -ab + b²
= a² - 2ab + b²

Now,

( x - 7 )²

$= ( {x}^{2} - 2(x)(7) + {7}^{2}) \\ \\ = ( {x}^{2} - 14x + 49)$
Therefore, ( x - 7 )² = x² + 49 - 14x

Hope helped! :)
