Question

(5x + 11)^2 - (5x - 11)^2 = 220x​

Answer 1

Answer:

hence proved

Step-by-step explanation

(5x+11)²-(5x-11)²=220x

(25x²+110x+121)-(25x²-110x+121)=220x

25x²+110x+121-25x²+110x-121=220x

25x²-25x²+121-121+110x+110x=220x

110x+110x=220x

220x=220x

Answer 2

Step-by-step explanation:

by usingi identity, (a+b)^2 and (a-b)^2

25x^2+121+110x-(25x^2+121-110x)=220x

25x^2+121+110x-25x^2-121+110x=220x

220x=220x

hence, proved.
