y^{2} - 4 y - 100 = 0

y = 2 (1 + 26), y = 2 (1 - 26)

Decimal Notation

y = 12.19803 \dots, y = - 8.19803 \dots

Solution steps

y^{2} - 4 y - 100 = 0

Solve with the quadratic formula

y_{1, 2} = \frac{- ( - 4 ) \pm ( - 4 ) ^{2} - 4 \cdot 1 \cdot ( - 100 )}{2 \cdot 1}

(- 4)^{2} - 4 \cdot 1 \cdot (- 100) = 426

y_{1, 2} = \frac{- ( - 4 ) \pm 4 26}{2 \cdot 1}

Separate the solutions

y_{1} = \frac{- ( - 4 ) + 4 26}{2 \cdot 1}, y_{2} = \frac{- ( - 4 ) - 4 26}{2 \cdot 1}

y = \frac{- ( - 4 ) + 4 26}{2 \cdot 1} : 2 (1 + 26)

y = \frac{- ( - 4 ) - 4 26}{2 \cdot 1} : 2 (1 - 26)

The solutions to the quadratic equation are:

y = 2 (1 + 26), y = 2 (1 - 26)

\frac{z}{- 4} = 16

2 - 4 y^{3} + 5 y^{3} + y^{3} + 2 + 5 x^{3} + 2

- 6 < 2 x - 3 < 4

\frac{1}{i ^{- 26}}
