Solve 63-2y=y^2 - ScanMath

Evaluate

63 - 2 y = y^{2}

Swap the sides

y^{2} = 63 - 2 y

Move the expression to the left side

y^{2} - 63 + 2 y = 0

Factor the expression

More Steps

(y - 7) (y + 9) = 0

When the product of factors equals 0,at least one factor is 0

y - 7 = 0 y + 9 = 0

Solve the equation for y

More Steps

y = 7 y + 9 = 0

Solve the equation for y

More Steps

y = 7 y = - 9

Solution

y_{1} = - 9, y_{2} = 7
