factor 10n^2-n-2

factor

10 n^{2} - n - 2

(5 n + 2) (2 n - 1)

Solution steps

10 n^{2} - n - 2

Break the expression into groups

= (10 n^{2} + 4 n) + (- 5 n - 2)

Factor out

2 n

from

10 n^{2} + 4 n : 2 n (5 n + 2)

Factor out

- 1

from

- 5 n - 2 : - (5 n + 2)

= 2 n (5 n + 2) - (5 n + 2)

Factor out common term

(5 n + 2) : (5 n + 2) (2 n - 1)

= (5 n + 2) (2 n - 1)

5 y^{- 2}

ln (x + 1)

5 - (- 2 a + 3) + 4 (1 - a)

x^{4} - x^{2} + 2 x - 1

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