factor 10x^2-x-2

factor

10 x^{2} - x - 2

(5 x + 2) (2 x - 1)

Solution steps

10 x^{2} - x - 2

Break the expression into groups

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

Factor out

2 x

from

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

Factor out

- 1

from

- 5 x - 2 : - (5 x + 2)

= 2 x (5 x + 2) - (5 x + 2)

Factor out common term

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

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

(n^{3})^{3} \cdot 2 n^{- 1}

2 a - 7 = - 15

4 x + 1 > 10

4 x - 7 = 2 x + 14

(- \frac{1}{5}) (t + 6) - 2 = 3 t + \frac{2}{3}
