Question 217681: (4x+3/2y)^2
Answer by RAY100(1637)   (Show Source):
You can put this solution on YOUR website! (4x+3/2y)^2 = (4x+3/2y)(4x+3/2y)
.
use FOIL
.
16x^2 + 6xy +6xy +9/4 y^2
.
16x^2 +12xy +9/4 y^2
.
.
check,,,,let x=2,,,y=3,,,,both original and answer = (8+4.5)^2 = 156.25
.
16(4) +12*2*3 +9/4(9)= 64 +72 + 81/4 = 156.25,,,ok
