2y^2-8y-10=0

Solution

2 y^{2} - 8 y - 10 = 0

Solution

y = 5, y = - 1

Solution steps

2 y^{2} - 8 y - 10 = 0

Solve with the quadratic formula

y_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 2 ( - 10 )}{2 \cdot 2}

(- 8)^{2} - 4 \cdot 2 (- 10) = 12

y_{1, 2} = \frac{- ( - 8 ) \pm 12}{2 \cdot 2}

Separate the solutions

y_{1} = \frac{- ( - 8 ) + 12}{2 \cdot 2}, y_{2} = \frac{- ( - 8 ) - 12}{2 \cdot 2}

y = \frac{- ( - 8 ) + 12}{2 \cdot 2} : 5

y = \frac{- ( - 8 ) - 12}{2 \cdot 2} : - 1

The solutions to the quadratic equation are:

y = 5, y = - 1
