factor x^2-1+x^2-x-2

factor

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

(x + 1) (2 x - 3)

Solution steps

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

Group like terms

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

Add similar elements:

x^{2} + x^{2} = 2 x^{2}

= 2 x^{2} - x - 1 - 2

Subtract the numbers:

- 1 - 2 = - 3

= 2 x^{2} - x - 3

Break the expression into groups

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

Factor out

2 x

from

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

Factor out

- 3

from

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

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

Factor out common term

x + 1

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

(2 r)^{2} + 12 r + 9

(cosh (2 x))^{2}

(2Δ x) - 1

9 x^{(2)}

2.6 x^{2} + (- 6.1) x + (- 2.6)
