3 x^{2} - 6 = - 7 x

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

Decimal Notation

x = 0.66666 \dots, x = - 3

Solution steps

3 x^{2} - 6 = - 7 x

Move

7 x

to the left side

3 x^{2} - 6 + 7 x = 0

Write in the standard form

a x^{2} + b x + c = 0

3 x^{2} + 7 x - 6 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 3 ( - 6 )}{2 \cdot 3}

7^{2} - 4 \cdot 3 (- 6) = 11

x_{1, 2} = \frac{- 7 \pm 11}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 7 + 11}{2 \cdot 3}, x_{2} = \frac{- 7 - 11}{2 \cdot 3}

x = \frac{- 7 + 11}{2 \cdot 3} : \frac{2}{3}

x = \frac{- 7 - 11}{2 \cdot 3} : - 3

The solutions to the quadratic equation are:

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

4 p^{2} - 28 p + 49

\frac{1 - \frac{1}{16}}{\frac{1}{16}}

5^{\frac{5}{2}}

(\frac{a ^{3}}{5 m})^{- 4}

x + 6 < 5 x - 6
