3 x^{2} - 7 x = 20

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

Decimal Notation

x = 4, x = - 1.66666 \dots

Solution steps

3 x^{2} - 7 x = 20

Move

20

to the left side

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}

9 (u - 2) + 1.5 u = 8.25

\frac{\frac{6}{5}}{( - \frac{1}{15} )}

6 x^{2} - 5 = 0

\frac{7}{12} = \frac{x}{9}

x^{2} - x - 2
