simplify (8k^3+18k^2-2k)/(-2k)

simplify

\frac{8 k ^{3} + 18 k ^{2} - 2 k}{- 2 k}

- 4 k^{2} - 9 k + 1

Solution steps

\frac{8 k ^{3} + 18 k ^{2} - 2 k}{- 2 k}

Factor

8 k^{3} + 18 k^{2} - 2 k : 2 k (4 k^{2} + 9 k - 1)

= \frac{2 k ( 4 k ^{2} + 9 k - 1 )}{- 2 k}

Cancel the common factor:

2

= \frac{k ( 4 k ^{2} + 9 k - 1 )}{- k}

Cancel the common factor:

k

= \frac{4 k ^{2} + 9 k - 1}{- 1}

Apply the fraction rule:

\frac{a}{- 1} = - a

= - (4 k^{2} + 9 k - 1)

Simplify

- (4 k^{2} + 9 k - 1) : - 4 k^{2} - 9 k + 1

= - 4 k^{2} - 9 k + 1

\frac{5}{5 a ^{2} b}

\frac{1}{2} + \frac{7}{5}

2 (2 x + 3) + 3

\frac{( - 2 s ^{3} ) ^{4}}{5 s ^{- 1}}

(x + 4) (x - 4) (x + 4)
