expand the following using suitable identities (×+11)(×+11)
jaiho9:
(x+11)(x+11)=(x+11)^2. identity (a+b)^2=a^2+b^2+2ab ,x^+(11)^2+2*11*x=x^2+121+22x

Hi, here the answer:-
(x+11)(x+11)
Using identity:
(a+b)(a+b)=(a+b)^2=a^2+b^2+2ab
(x+11)^2
x^2+121+2×11×x
x^2+121+22x
It can be written as:-
x^2+22x+121
May it help...
(x+11)(x+11)
Using identity:

(x+11)^2
x^2+121+2×11×x
x^2+121+22x
It can be written as:-
x^2+22x+121

(x+11)(x+11)
=(x+11)^2
now (a+b)^2 = a^2 + 2ab + b^2
(x+11)^2 = x^2 + 2 × x × 11 + 11^2
= x^2 + 22x + 121
=(x+11)^2
now (a+b)^2 = a^2 + 2ab + b^2
(x+11)^2 = x^2 + 2 × x × 11 + 11^2
= x^2 + 22x + 121
