factor r^2-rg-20g^2

factor

r^{2} - r g - 20 g^{2}

(r + 4 g) (r - 5 g)

Solution steps

r^{2} - r g - 20 g^{2}

Break the expression into groups

= (r^{2} + 4 r g) + (- 5 r g - 20 g^{2})

Factor out

r

from

r^{2} + 4 r g : r (r + 4 g)

Factor out

- 5 g

from

- 5 r g - 20 g^{2} : - 5 g (r + 4 g)

= r (r + 4 g) - 5 g (r + 4 g)

Factor out common term

r + 4 g

= (r + 4 g) (r - 5 g)

x^{3} - 7 x^{2} - 25 x + 175

- \frac{1}{2 ( \frac{1}{16} ) ^{\frac{3}{2}}}

- \frac{3}{4} m - \frac{1}{2} = 2 + \frac{1}{4} m

\frac{3}{2 x - 5} \leq 0

0 = x^{2} - 8 x + 16
