factor 6x^2-x-1

factor

6 x^{2} - x - 1

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

Solution steps

6 x^{2} - x - 1

Break the expression into groups

= (6 x^{2} + 2 x) + (- 3 x - 1)

Factor out

2 x

from

6 x^{2} + 2 x : 2 x (3 x + 1)

Factor out

- 1

from

- 3 x - 1 : - (3 x + 1)

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

Factor out common term

(3 x + 1) : (3 x + 1) (2 x - 1)

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

3 z^{2} + 8 z - 3

\frac{3 x}{8} - \frac{4 x}{3} = 4

4 x^{2} + 9 x - 1 = 0

- \frac{5}{3} \cdot (- \frac{1}{7})

\frac{1}{1 + e ^{- 0.5}}
