36 u = 9 u^{2}

u = 0, u = 4

Solution steps

36 u = 9 u^{2}

Move

9 u^{2}

to the left side

36 u - 9 u^{2} = 0

Factor

36 u - 9 u^{2} : - 9 u (u - 4)

- 9 u (u - 4) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

u = 0 or u - 4 = 0

Solve

u - 4 = 0 : u = 4

The solutions to the quadratic equation are:

u = 0, u = 4

3 x^{2} = 5 x - 3

- x^{2} - 12 = 0

4^{2} + 1 2^{2} = x^{2}

64 x^{2} - 80 x

4 = 3 x^{2} - 26 x + 44
