Answer :
Ok to start off, For the future use ^ to show exponents, example; y^2
y^2 + 4y +4 = 7
subtract 7 from both sides making one side equal zero, this now looks like a quadratic equation, right? Solve.
y=−2±√7
y^2 + 4y +4 = 7
subtract 7 from both sides making one side equal zero, this now looks like a quadratic equation, right? Solve.
y=−2±√7
