factor x^3+3x^2-6x-8

factor

x^{3} + 3 x^{2} - 6 x - 8

(x + 1) (x - 2) (x + 4)

Solution steps

x^{3} + 3 x^{2} - 6 x - 8

Use the rational root theorem

= (x + 1) \frac{x ^{3} + 3 x ^{2} - 6 x - 8}{x + 1}

\frac{x ^{3} + 3 x ^{2} - 6 x - 8}{x + 1} = x^{2} + 2 x - 8

= (x + 1) (x^{2} + 2 x - 8)

Factor

x^{2} + 2 x - 8 : (x - 2) (x + 4)

= (x + 1) (x - 2) (x + 4)

60 - 2 x^{2} = x^{2} + 9 x + 30

\frac{5 n + 15}{4 n + 8} \cdot \frac{2 n + 4}{3 n + 9}

\frac{1}{x + 2} \geq 0

ab + 6 b - 2 a - 12

3 r^{2} + 2 r = 0.375
