(x/2+3y/4)*(x/2+3y/4)=(x/2+3y/4)^2

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

(x/2+3y/4)^2= (x/2)^2+(3y/4)^2+2*x/2*3y/4

                   = x^2/4+9y^2/16+3xy/4

here (x/2+3y/4) * (x/2+3y/4)
we can use ( a+b) (a+b) = a^2+b^2
(x/2)^2+(3y/4)^2
x^2/4 + 9y^2/16
4x^2 + 9y^2

sagarkes: make me BRAINLIEST
sbspdwivedi: This is wrong. (a+b)(a+b)=a^2+b^2+2ab. First of all, multiply "a" with "a" and "b" both. Then multiply "b" with "a" and "b" both. As a result, a^2+b^2+2ab is formed.
