y^{2} + 8 (y - 1) = 3

y = - 4 + 33, y = - 4 - 33

Solution steps

y^{2} + 8 (y - 1) = 3

Expand

y^{2} + 8 (y - 1) : y^{2} + 8 y - 8

y^{2} + 8 y - 8 = 3

Move

3

to the left side

y^{2} + 8 y - 11 = 0

Solve with the quadratic formula

y_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 1 \cdot ( - 11 )}{2 \cdot 1}

8^{2} - 4 \cdot 1 \cdot (- 11) = 63

y_{1, 2} = \frac{- 8 \pm 6 3}{2 \cdot 1}

Separate the solutions

y_{1} = \frac{- 8 + 6 3}{2 \cdot 1}, y_{2} = \frac{- 8 - 6 3}{2 \cdot 1}

y = \frac{- 8 + 6 3}{2 \cdot 1} : - 4 + 33

y = \frac{- 8 - 6 3}{2 \cdot 1} : - 4 - 33

The solutions to the quadratic equation are:

y = - 4 + 33, y = - 4 - 33
