Question

the value of (a+b) ki power 2 - (a-b) ki power 2​

Answer 1

Answer:

X, Y, A, B are the most commonly used letters that represent algebraic problems and ... a2 – b2 = (a – b)(a + b); (a + b)2 = a2 + 2ab + b2; a2 + b2 = (a + b) 2 – 2ab ... Example 1: Find out the value of 52 – 32

Answer 2

Answer:

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

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

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

aa^2+b^2+2ab-a^2-b^2+2ab

=4ab

THE ANSWER IS 4AB
