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

r = - \frac{7}{6}

Decimal Notation

r = - 1.16666 \dots

Solution steps

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

Solve with the quadratic formula

r_{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

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

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

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

r = - \frac{7}{6}

The solution to the quadratic equation is:

r = - \frac{7}{6}
