36 x^{2} + 84 x = - 49

x = - \frac{7}{6}

Decimal Notation

x = - 1.16666 \dots

Solution steps

36 x^{2} + 84 x = - 49

Move

49

to the left side

36 x^{2} + 84 x + 49 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 84 \pm 8 4 ^{2} - 4 \cdot 36 \cdot 49}{2 \cdot 36}

8 4^{2} - 4 \cdot 36 \cdot 49 = 0

x_{1, 2} = \frac{- 84 \pm 0}{2 \cdot 36}

x = \frac{- 84}{2 \cdot 36}

\frac{- 84}{2 \cdot 36} = - \frac{7}{6}

x = - \frac{7}{6}

The solution to the quadratic equation is:

x = - \frac{7}{6}

- 81 = 6 u - 13 u - 18
