factor 16x^3+80x^2-9x-45

factor

16 x^{3} + 80 x^{2} - 9 x - 45

(x + 5) (4 x + 3) (4 x - 3)

Solution steps

16 x^{3} + 80 x^{2} - 9 x - 45

= (16 x^{3} + 80 x^{2}) + (- 9 x - 45)

Factor out

16 x^{2}

from

16 x^{3} + 80 x^{2} : 16 x^{2} (x + 5)

Factor out

- 9

from

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

= 16 x^{2} (x + 5) - 9 (x + 5)

Factor out common term

x + 5

= (x + 5) (16 x^{2} - 9)

Factor

16 x^{2} - 9 : (4 x + 3) (4 x - 3)

= (x + 5) (4 x + 3) (4 x - 3)

(i + 2)^{3}

(42) (9 - 7)

f (x - 3)

f (x + 3)

\frac{1}{18}
