Question 55344: I tried answering but cant come up with an answer. Please help me to solve and check.
sqrt 2y+7+4=y
\/2y+7+4=y
Answer by checkley71(8403) (Show Source): You can put this solution on YOUR website!
SQRT(2Y+7+4)=Y
SQRT(2Y+11)=Y
NOW SQUARE BOTH SIDES
2Y+11=Y^2
Y^2-2Y-11=0
USING THE QUADRATIC EQUATION WE GET
Y=(2+-SQRT48)/2
Y=2+-4SQRT6)/2
Y=1+-2SQRT6 OR
Y=4.464
Y=-2.464
