Answer 1

Question:-

find the following by using the second identity (x-7)²

${\blue{\underline{\underline{\bold{Answer:-}}}}}$

since we have given that

(x - 7)²

As we know the identity:-

(a-b)²= a²+b²-2ab

so , it becomes ,

(x-7)²=x²+7²- 2×7×x

(x-7)²= x²+49-14x

or x²-14x+49

hence, x²-14x+49 is the square of (x - 7)²
