X^{2} + 11 X + 18 = 0

X = - 2, X = - 9

Solution steps

X^{2} + 11 X + 18 = 0

Solve with the quadratic formula

X_{1, 2} = \frac{- 11 \pm 1 1 ^{2} - 4 \cdot 1 \cdot 18}{2 \cdot 1}

1 1^{2} - 4 \cdot 1 \cdot 18 = 7

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

Separate the solutions

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

X = \frac{- 11 + 7}{2 \cdot 1} : - 2

X = \frac{- 11 - 7}{2 \cdot 1} : - 9

The solutions to the quadratic equation are:

X = - 2, X = - 9

x^{2} - 8 x - 17 = 0

5 x^{2} - 10 x - 12 = 0

1 2^{2} + x^{2} = 1 4^{2}

- 4 x^{2} = 48

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