 Question 45307: Directions: Solve the radical equation. Check all propsed solutions. square root y^2-3y+18=y+2 The square root is over y^2-3y+18, thats it, not the y+2Answer by fractalier(2101)   (Show Source): You can put this solution on YOUR website!Okay first we square both sides...we get sqrt( y^2-3y+18 ) = y + 2 y^2 - 3y + 18 = y^2 + 4y + 4 now collect terms and solve...we get -3y + 18 = 4y + 4 14 = 7y y = 2 you have to check these by plugging 2 in for y in the original...turns out okay...
