5 u^{2} = 15 u

u = 0, u = 3

Solution steps

5 u^{2} = 15 u

Move

15 u

to the left side

5 u^{2} - 15 u = 0

Factor

5 u^{2} - 15 u : 5 u (u - 3)

5 u (u - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

u = 0 or u - 3 = 0

Solve

u - 3 = 0 : u = 3

The solutions to the quadratic equation are:

u = 0, u = 3

\frac{4}{7} \cdot 14

\frac{3 ^{3}}{3}

\frac{1}{2} \cdot (\frac{1}{4})^{0}

x^{2} + 13 x + 42 = 0

1 + 3 x = x - 5
