Question

solve: the square of 6g = (j+y) for g.

Answer 1

\[solve: \sqrt{6g}=\left( j+y \right) for g\]

Answer 2

square root right?

Answer 3

yes, i just added the equation.

Answer 4

square both sides
6g = (j + y)^2
now its easy

Answer 5

divide both sides by 6

Answer 6

when i did that, i came up with g= (j+y)^2 / 6,,, but the answer is g= (j^2 +2jy+y^2) / 6 I don't get how to get the correct answer

Answer 7

ah - thats same thing - they've expanded (j + y)^2
which comes to ( j^2 + 2jy + y^2)

Answer 8

so answer is ( j^2 + 2jy + y^2) / 6

Answer 9

oh i see now,, tyyt!!!
