9 x^{2} - 15 x - 6 = 0

x = 2, x = - \frac{1}{3}

Decimal

x = 2, x = - 0.33333 \dots

Solution steps

9 x^{2} - 15 x - 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 15 ) \pm ( - 15 ) ^{2} - 4 \cdot 9 ( - 6 )}{2 \cdot 9}

(- 15)^{2} - 4 \cdot 9 (- 6) = 21

x_{1, 2} = \frac{- ( - 15 ) \pm 21}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- ( - 15 ) + 21}{2 \cdot 9}, x_{2} = \frac{- ( - 15 ) - 21}{2 \cdot 9}

x = \frac{- ( - 15 ) + 21}{2 \cdot 9} : 2

x = \frac{- ( - 15 ) - 21}{2 \cdot 9} : - \frac{1}{3}

The solutions to the quadratic equation are:

x = 2, x = - \frac{1}{3}

(40 - x) (60 - x) = 800

2 x^{2} + 160 = 36 x

y, y^{2} + 2 y + 1 = 0

t, A t - \frac{( B t ^{2} )}{2} = 0

(2 x - 1) (x + 2) = 8 x - 4
