30 s^{2} + 13 s - 10 = 0

s = \frac{2}{5}, s = - \frac{5}{6}

Decimal Notation

s = 0.4, s = - 0.83333 \dots

Solution steps

30 s^{2} + 13 s - 10 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- 13 \pm 1 3 ^{2} - 4 \cdot 30 ( - 10 )}{2 \cdot 30}

1 3^{2} - 4 \cdot 30 (- 10) = 37

s_{1, 2} = \frac{- 13 \pm 37}{2 \cdot 30}

Separate the solutions

s_{1} = \frac{- 13 + 37}{2 \cdot 30}, s_{2} = \frac{- 13 - 37}{2 \cdot 30}

s = \frac{- 13 + 37}{2 \cdot 30} : \frac{2}{5}

s = \frac{- 13 - 37}{2 \cdot 30} : - \frac{5}{6}

The solutions to the quadratic equation are:

s = \frac{2}{5}, s = - \frac{5}{6}

90 = \frac{n ( n - 3 )}{2}

x^{2} - 6 x - 33 = - 4 x + 2

4 x^{2} + 6 x = 4

x - 2 x^{2} + 13 x - 21 = 0

x = \frac{1}{2} x^{2} - \frac{1}{2} x + 1
