factor x^3-15-5x+3x^2

factor

x^{3} - 15 - 5 x + 3 x^{2}

(x + 3) (x^{2} - 5)

Solution steps

x^{3} - 15 - 5 x + 3 x^{2}

= (x^{3} + 3 x^{2}) + (- 5 x - 15)

Factor out

x^{2}

from

x^{3} + 3 x^{2} : x^{2} (x + 3)

Factor out

- 5

from

- 5 x - 15 : - 5 (x + 3)

= x^{2} (x + 3) - 5 (x + 3)

Factor out common term

x + 3

= (x + 3) (x^{2} - 5)

\frac{3}{x + 6} + \frac{7}{x - 2}

\frac{x ^{2} - 4 x - 60}{x ^{2} - 2 x - 48}

2 (a + 3 b)

(\frac{2}{3})^{2} \times (\frac{2}{3})^{3}
