9 x^{2} + 33 x = - 30

x = - \frac{5}{3}, x = - 2

Decimal Notation

x = - 1.66666 \dots, x = - 2

Solution steps

9 x^{2} + 33 x = - 30

Move

30

to the left side

9 x^{2} + 33 x + 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 33 \pm 3 3 ^{2} - 4 \cdot 9 \cdot 30}{2 \cdot 9}

3 3^{2} - 4 \cdot 9 \cdot 30 = 3

x_{1, 2} = \frac{- 33 \pm 3}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- 33 + 3}{2 \cdot 9}, x_{2} = \frac{- 33 - 3}{2 \cdot 9}

x = \frac{- 33 + 3}{2 \cdot 9} : - \frac{5}{3}

x = \frac{- 33 - 3}{2 \cdot 9} : - 2

The solutions to the quadratic equation are:

x = - \frac{5}{3}, x = - 2

x^{2} - 10 x = 26

1 + 2 + n = \frac{n ( n + 1 )}{2}

5 x^{2} + 8 x - 15 = 0

x, y^{(3)} = 8 x^{2} + 1

6 x^{2} + 6 x - 252 = 0
