factor 25r^3+30r^2-30r-36

factor

25 r^{3} + 30 r^{2} - 30 r - 36

(5 r + 6) (5 r^{2} - 6)

Solution steps

25 r^{3} + 30 r^{2} - 30 r - 36

= (25 r^{3} + 30 r^{2}) + (- 30 r - 36)

Factor out

5 r^{2}

from

25 r^{3} + 30 r^{2} : 5 r^{2} (5 r + 6)

Factor out

- 6

from

- 30 r - 36 : - 6 (5 r + 6)

= 5 r^{2} (5 r + 6) - 6 (5 r + 6)

Factor out common term

5 r + 6

= (5 r + 6) (5 r^{2} - 6)

- 10 \cdot 1.7

- x^{2} + x + 12

\frac{1}{4 - 3 i}

3 (\frac{x}{- 5} + 6) < 30

2 + \frac{1}{3}
