3 x^{2} - 15 x - 2 = 0

x = \frac{15 + 249}{6}, x = \frac{15 - 249}{6}

Decimal Notation

x = 5.12995 \dots, x = - 0.12995 \dots

Solution steps

3 x^{2} - 15 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 15 ) \pm ( - 15 ) ^{2} - 4 \cdot 3 ( - 2 )}{2 \cdot 3}

(- 15)^{2} - 4 \cdot 3 (- 2) = 249

x_{1, 2} = \frac{- ( - 15 ) \pm 249}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 15 ) + 249}{2 \cdot 3}, x_{2} = \frac{- ( - 15 ) - 249}{2 \cdot 3}

x = \frac{- ( - 15 ) + 249}{2 \cdot 3} : \frac{15 + 249}{6}

x = \frac{- ( - 15 ) - 249}{2 \cdot 3} : \frac{15 - 249}{6}

The solutions to the quadratic equation are:

x = \frac{15 + 249}{6}, x = \frac{15 - 249}{6}

q, q^{2} + 3 pq = 22

\frac{( x + 5 ) ^{2}}{144} - \frac{( x - 2 ) ^{2}}{25} = 1

2 x^{2} + 8 x + 134 = 0

20 x^{2} - 5 x - 12 = 0

x^{2} + 12 x - 8 = 0
