Solve 0=117-4y-y^(2)

Evaluate

0 = 117 - 4 y - y^{2}

Swap the sides

117 - 4 y - y^{2} = 0

Factor the expression

More Steps

(9 - y) (13 + y) = 0

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

9 - y = 0 13 + y = 0

Solve the equation for y

More Steps

y = 9 13 + y = 0

Solve the equation for y

More Steps

y = 9 y = - 13

Solution

y_{1} = - 13, y_{2} = 9
