9 x^{2} = - 15 x

x = 0, x = - \frac{5}{3}

Decimal Notation

x = 0, x = - 1.66666 \dots

Solution steps

9 x^{2} = - 15 x

Move

15 x

to the left side

9 x^{2} + 15 x = 0

Factor

9 x^{2} + 15 x : 3 x (3 x + 5)

3 x (3 x + 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or 3 x + 5 = 0

Solve

3 x + 5 = 0 : x = - \frac{5}{3}

The solutions to the quadratic equation are:

x = 0, x = - \frac{5}{3}

x^{2} - 121 = 0

x^{2} + 2 x - 48 = 0

19 + 2 x^{2} = 21

x, x^{2} + 4 x + 10 = 0

lo g_{10} (3) x^{2} - lo g_{10} (3) = 2
