Question

expansion based on algebraic form

[3a+4b] [3a+4b]​

Answer 1

Answer:

9a^2+16b^2+24ab

Step-by-step explanation:

We know,

(x+y)(x-y)= x^2+y^2+2xy (This formula can be simply written as (x+y)^2)

We substitute the values as

x=3a

y=4b

Therefore according to the formula

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

(3a+4b)(3a-4b)=(3a)^2+(4b)^+2(3a)(4b)

=9a^2+16b^2+24ab
