9 x^{2} = - 30 x - 25

x = - \frac{5}{3}

Decimal Notation

x = - 1.66666 \dots

Solution steps

9 x^{2} = - 30 x - 25

Move

25

to the left side

9 x^{2} + 25 = - 30 x

Move

30 x

to the left side

9 x^{2} + 25 + 30 x = 0

Write in the standard form

a x^{2} + b x + c = 0

9 x^{2} + 30 x + 25 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 \cdot 9 \cdot 25}{2 \cdot 9}

3 0^{2} - 4 \cdot 9 \cdot 25 = 0

x_{1, 2} = \frac{- 30 \pm 0}{2 \cdot 9}

x = \frac{- 30}{2 \cdot 9}

\frac{- 30}{2 \cdot 9} = - \frac{5}{3}

x = - \frac{5}{3}

The solution to the quadratic equation is:

x = - \frac{5}{3}

- 3 x < 15

6 x^{2} - 4 x - 3 = 0

3 x^{2} + 2 < 4 x^{2}

3 (\frac{3}{4})

- \frac{1}{2} x^{- 2} y^{- 4}
