3 x^{2} - 4 x - 55 = 0

x = 5, x = - \frac{11}{3}

Decimal Notation

x = 5, x = - 3.66666 \dots

Solution steps

3 x^{2} - 4 x - 55 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 4 ) \pm ( - 4 ) ^{2} - 4 \cdot 3 ( - 55 )}{2 \cdot 3}

(- 4)^{2} - 4 \cdot 3 (- 55) = 26

x_{1, 2} = \frac{- ( - 4 ) \pm 26}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 4 ) + 26}{2 \cdot 3}, x_{2} = \frac{- ( - 4 ) - 26}{2 \cdot 3}

x = \frac{- ( - 4 ) + 26}{2 \cdot 3} : 5

x = \frac{- ( - 4 ) - 26}{2 \cdot 3} : - \frac{11}{3}

The solutions to the quadratic equation are:

x = 5, x = - \frac{11}{3}

5 x^{2} - 45 x = 0

x^{2} + 3 x = 7

y^{2} - 9 y

x, (y - 1)^{3} = x^{2}

3 x^{2} = 8 x - 7
