factor x^3+5x^2-9x-45

factor

x^{3} + 5 x^{2} - 9 x - 45

(x + 5) (x + 3) (x - 3)

Solution steps

x^{3} + 5 x^{2} - 9 x - 45

= (x^{3} + 5 x^{2}) + (- 9 x - 45)

Factor out

x^{2}

from

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

Factor out

- 9

from

- 9 x - 45 : - 9 (x + 5)

= x^{2} (x + 5) - 9 (x + 5)

Factor out common term

x + 5

= (x + 5) (x^{2} - 9)

Factor

x^{2} - 9 : (x + 3) (x - 3)

= (x + 5) (x + 3) (x - 3)

4 x^{2} + 7 x + 3

5 y + 13 = - 43 - 3 y

x^{2} - x - 6 = - 6

- \frac{3}{8} - (- \frac{1}{12})

\frac{3 + 1}{3 - 1}
