9 x^{2} = 27 x

x = 0, x = 3

Solution steps

9 x^{2} = 27 x

Move

27 x

to the left side

9 x^{2} - 27 x = 0

Factor

9 x^{2} - 27 x : 9 x (x - 3)

9 x (x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x - 3 = 0

Solve

x - 3 = 0 : x = 3

The solutions to the quadratic equation are:

x = 0, x = 3

x^{2} - x - 2 \leq 0

\frac{x}{3} \geq - 6

1.2 x + 3.6 \leq 9.6

\frac{∣ x + 5 ∣}{x ^{2} - 6 x + 8} \leq 2

81 x^{2} = 4
