Question

simplify: (3/4x - 4/3y)^2 +2xy​

Answer 1

Step-by-step explanation:

(3/4x-4/3y)²+2xy=(3/4)²+(4/3)²-2(3/4)(4/3)xy -2xy

9/16x²+16/9y²-2xy+2xy

9/16x²+16/9y²

Answer 2

Answer:

(3/4x-4/3y)^2+2 xy

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

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

= 9/16x ^2+16/9y^2 -2 x y

9/16x^2 +16/9y^2 -2 xy + 2 xy

9/16x^2 +16/9 y^2 (-2 xy and +2 xy is canceling)

i hope this is right
