2 X^{2} + 11 X + 5 = 0

X = - \frac{1}{2}, X = - 5

Decimal Notation

X = - 0.5, X = - 5

Solution steps

2 X^{2} + 11 X + 5 = 0

Solve with the quadratic formula

X_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 \cdot 2 \cdot 5}{2 \cdot 2}

1 1^{2} - 4 \cdot 2 \cdot 5 = 9

X_{1, 2} = \frac{- 11 \pm 9}{2 \cdot 2}

Separate the solutions

X_{1} = \frac{- 11 + 9}{2 \cdot 2}, X_{2} = \frac{- 11 - 9}{2 \cdot 2}

X = \frac{- 11 + 9}{2 \cdot 2} : - \frac{1}{2}

X = \frac{- 11 - 9}{2 \cdot 2} : - 5

The solutions to the quadratic equation are:

X = - \frac{1}{2}, X = - 5

2 x^{2} + 6 x + 18 = 0

k^{2} - 9 k + 8 = 0

0 = 3 x^{2} - 10 x - 8

3 x^{2} - 10 x - 3 = 0

r^{2} + 2 r + 9 = 0
