factor k^2-6k-16

factor

k^{2} - 6 k - 16

(k + 2) (k - 8)

Solution steps

k^{2} - 6 k - 16

Break the expression into groups

= (k^{2} + 2 k) + (- 8 k - 16)

Factor out

k

from

k^{2} + 2 k : k (k + 2)

Factor out

- 8

from

- 8 k - 16 : - 8 (k + 2)

= k (k + 2) - 8 (k + 2)

Factor out common term

k + 2

= (k + 2) (k - 8)

192 x^{8} + 81 x^{5} y^{3}

4 x^{- \frac{1}{2}}

(2 x + 1) (x - 3) = (x + 1) (x - 1) - 8

\frac{a ^{- \frac{1}{4}} a ^{\frac{3}{2}}}{a ^{\frac{1}{3}}}

49 x^{2} - 140 x + 100
