y^2-6y-7=0

Solution

y^{2} - 6 y - 7 = 0

Solution

y = 7, y = - 1

Solution steps

y^{2} - 6 y - 7 = 0

Solve with the quadratic formula

y_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 1 \cdot ( - 7 )}{2 \cdot 1}

(- 6)^{2} - 4 \cdot 1 \cdot (- 7) = 8

y_{1, 2} = \frac{- ( - 6 ) \pm 8}{2 \cdot 1}

Separate the solutions

y_{1} = \frac{- ( - 6 ) + 8}{2 \cdot 1}, y_{2} = \frac{- ( - 6 ) - 8}{2 \cdot 1}

y = \frac{- ( - 6 ) + 8}{2 \cdot 1} : 7

y = \frac{- ( - 6 ) - 8}{2 \cdot 1} : - 1

The solutions to the quadratic equation are:

y = 7, y = - 1
