Answer 1

Answer:

$x = \frac{11}{4}$

Step-by-step explanation:

here,$(2x + 11)^{2} - 88x = (2x - 11)^{2}$

     ⇒ $4x^{2} + 121 - 88x = 4x^{2} - 121$

     ⇒ $4x^{2} - 4x^{2} +88x = 121 + 121$

     ⇒ $x = \frac{242}{88}$

     ⇒ $x = \frac{11}{4}$

hope it will help you.

Answer 2

Answer:

LHS=RHS

Step-by-step explanation:

LHS.

use (a)²+2ab+(b)² formula.

= (2x)²+2(2x)(11)+(11)²-88x

= 4x²+44x+121-88x

=4x²-44x+121

RHS

use (a)²-2ab+(b)² formula

= (2x)²-2(2x)(11)+121

= 4x²-44x+121

so 4x²-44x+121 = 4x²-44x+121

therefore, LHS=RHS
