3 x^{2} - 7 x - 20 = 0

x = 4, x = - \frac{5}{3}

Decimal Notation

x = 4, x = - 1.66666 \dots

Solution steps

3 x^{2} - 7 x - 20 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 3 ( - 20 )}{2 \cdot 3}

(- 7)^{2} - 4 \cdot 3 (- 20) = 17

x_{1, 2} = \frac{- ( - 7 ) \pm 17}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 17}{2 \cdot 3}, x_{2} = \frac{- ( - 7 ) - 17}{2 \cdot 3}

x = \frac{- ( - 7 ) + 17}{2 \cdot 3} : 4

x = \frac{- ( - 7 ) - 17}{2 \cdot 3} : - \frac{5}{3}

The solutions to the quadratic equation are:

x = 4, x = - \frac{5}{3}

w - 15 = - 4

12 - 5

\frac{\frac{x}{y} - \frac{y}{x}}{\frac{1}{4 x ^{2}} - \frac{1}{4 y ^{2}}}

\frac{a + 3}{7 a + 21}

\frac{5 x ^{2} - 48 x}{4} + 34 = 0
