Question

solve (x-7)^2 by using the identity a^2-2*a*b+b^2
​

Answer 1

$\sf \: QUESTION \: : (x - 7) {}^{2}$

ANSWER:-

$\sf \: Using \: the \: identity \: a {}^{2} - 2a b + {b}^{2}$

Now putting A and B values in the formula , which gives

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

$= x {}^{2} - 14x + 49$

So , the solution of the given equation is

$x {}^{2} - 14x + 49$

HOPE IT HELPS ✌

Answer 2

Answer:

Equation is x² - 14x + 49.

Step-by-step explanation:

(x - 7)²

(x)² + 2(x)(-7) + (-7)²

x² - 14x + 49

So, our equation is x² - 14x + 49 through your given Identity (a² - 2ab + b²).
