2 x^{3} + 26 x^{2} + 84 x = 0

x = 0, x = - 6, x = - 7

Solution steps

2 x^{3} + 26 x^{2} + 84 x = 0

Factor

2 x^{3} + 26 x^{2} + 84 x : 2 x (x + 6) (x + 7)

2 x (x + 6) (x + 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 6 = 0 or x + 7 = 0

Solve

x + 6 = 0 : x = - 6

Solve

x + 7 = 0 : x = - 7

The solutions are

x = 0, x = - 6, x = - 7

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

z^{5} - 2 z^{4} - z^{3} + 6 z - 4 = 0

\frac{64}{81} = 4 q^{3}

- b + 3 - 1 = 3 x^{4}

x^{5} - 2 = - x
