factor 16r^3+28r^2-28r-49

factor

16 r^{3} + 28 r^{2} - 28 r - 49

(4 r + 7) (4 r^{2} - 7)

Solution steps

16 r^{3} + 28 r^{2} - 28 r - 49

= (16 r^{3} + 28 r^{2}) + (- 28 r - 49)

Factor out

4 r^{2}

from

16 r^{3} + 28 r^{2} : 4 r^{2} (4 r + 7)

Factor out

- 7

from

- 28 r - 49 : - 7 (4 r + 7)

= 4 r^{2} (4 r + 7) - 7 (4 r + 7)

Factor out common term

4 r + 7

= (4 r + 7) (4 r^{2} - 7)

\frac{x - 2}{x + 6} \leq 0

- 3 x + 12 x + 6 = 7 x + 30

\frac{n \cdot \frac{m}{r \cdot s} \cdot s}{k g \cdot m ^{2}}

22 = - \frac{3}{2} x

\frac{6 !}{3 ! 2 ! 1 !}
