Question

Using identities find the following:- a) (x+3) (x+3) b)(2x+5) (2y +5) c)(2a-7) (2a-7)​

Answer 1

Answer:

A {x+y} sq

B (x+a) (x+b)

C (x+y) sq

Answer 2

Step-by-step explanation:

a)x^2+6x+9

b)4xy+10x+10y+25

c)4a^2-28a+49

using identities

(x+y)^2=x^2+y^2+2xy

(x-y)^2=x^2-2xy+y^2

(x+a)(y+a)
