4 q^{2} + 16 q - 9 = 0

q = \frac{1}{2}, q = - \frac{9}{2}

Decimal Notation

q = 0.5, q = - 4.5

Solution steps

4 q^{2} + 16 q - 9 = 0

Solve with the quadratic formula

q_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 \cdot 4 ( - 9 )}{2 \cdot 4}

1 6^{2} - 4 \cdot 4 (- 9) = 20

q_{1, 2} = \frac{- 16 \pm 20}{2 \cdot 4}

Separate the solutions

q_{1} = \frac{- 16 + 20}{2 \cdot 4}, q_{2} = \frac{- 16 - 20}{2 \cdot 4}

q = \frac{- 16 + 20}{2 \cdot 4} : \frac{1}{2}

q = \frac{- 16 - 20}{2 \cdot 4} : - \frac{9}{2}

The solutions to the quadratic equation are:

q = \frac{1}{2}, q = - \frac{9}{2}
