- 5 x^{2} = 15 x

x = 0, x = - 3

Solution steps

- 5 x^{2} = 15 x

Move

15 x

to the left side

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

Factor

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

- 5 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

\frac{3 x}{2} + \frac{1}{4} (x - 2) = 10

(\frac{6}{7})^{- 2}

\frac{2 x + 5}{x + 1} > \frac{x + 1}{x - 1}

7 x y - 21 x z

∣ 4 x - 2 ∣ \geq x + 1
