Question

Please send the algebric formula like (a+b)^2 means a+b whole square etc

Answer 1

(a+b)^2= a^2+2ab+b^2
(a-b)^2=a^2-2ab+b^2
(a+b)(a-b)= a^2-b^2
(x+a)(x+b)= x^2+(a+b)x+ab

Answer 2

(a+b)^2= a^2+b^2+2ab...............................and..............................(a-b)^2=a^2+b^2 -2ab.......and....................a^2+b^2= (a+b)(a-b)
