y^2-7y-30=0

Solution

y^{2} - 7 y - 30 = 0

Solution

y = 10, y = - 3

Solution steps

y^{2} - 7 y - 30 = 0

Solve with the quadratic formula

y_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

(- 7)^{2} - 4 \cdot 1 \cdot (- 30) = 13

y_{1, 2} = \frac{- ( - 7 ) \pm 13}{2 \cdot 1}

Separate the solutions

y_{1} = \frac{- ( - 7 ) + 13}{2 \cdot 1}, y_{2} = \frac{- ( - 7 ) - 13}{2 \cdot 1}

y = \frac{- ( - 7 ) + 13}{2 \cdot 1} : 10

y = \frac{- ( - 7 ) - 13}{2 \cdot 1} : - 3

The solutions to the quadratic equation are:

y = 10, y = - 3
