9 x^{3} = 12 x^{4}

x = 0, x = \frac{3}{4}

Decimal

x = 0, x = 0.75

Solution steps

9 x^{3} = 12 x^{4}

Move

12 x^{4}

to the left side

9 x^{3} - 12 x^{4} = 0

Factor

9 x^{3} - 12 x^{4} : - 3 x^{3} (4 x - 3)

- 3 x^{3} (4 x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or 4 x - 3 = 0

Solve

4 x - 3 = 0 : x = \frac{3}{4}

The solutions are

x = 0, x = \frac{3}{4}

3 x^{4} - 8 x^{2} + 5 = 0

3 x^{3} - 4 x^{2} - 27 x + 36 = 0

(x + 7)^{3} (x - 2 i) (x + 2 i) = 0

4 x^{3} + 7 x^{2} - 12 x - 21 = 0

x^{4} - 5 x^{2} + 6 x - 4 = 0
