how do I turn \[\sqrt{y}= x^{2}(x+7)\] into y=mx+b form?
anonymous
  • anonymous
well first I would distribute the \[x^2\] into the (x+7) then solve for y by squaring both sides.

  • anonymous
my bad its : \[y^{2}= x^{2} (x+7)\]
anonymous
  • anonymous
well then distribute the \[x2^\] then take the square root of both sides to solve for y. Remember when taking the square root you might need to account for the result being + or -

err \[x^2\]
