factor (x^2+x)-2

factor

(x^{2} + x) - 2

(x - 1) (x + 2)

Solution steps

(x^{2} + x) - 2

Remove parentheses:

(a) = a

= x^{2} + x - 2

Break the expression into groups

= (x^{2} - x) + (2 x - 2)

Factor out

x

from

x^{2} - x : x (x - 1)

Factor out

2

from

2 x - 2 : 2 (x - 1)

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

Factor out common term

x - 1

= (x - 1) (x + 2)

(sin (π t))^{2}

5 ab - 10 ab

(4 x)^{2} - 2 (4 x) - 15

sin (3 x + 3 h)

48 x^{4} - 18 x^{4}
