factor a^3+2a^2-a-2

Solution

factor

a^{3} + 2 a^{2} - a - 2

Solution

(a + 2) (a + 1) (a - 1)

Solution steps

a^{3} + 2 a^{2} - a - 2

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

Factor out

a^{2}

from

a^{3} + 2 a^{2} : a^{2} (a + 2)

Factor out

- 1

from

- a - 2 : - (a + 2)

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

Factor out common term

(a + 2) : (a + 2) (a^{2} - 1)

= (a + 2) (a^{2} - 1)

Factor

a^{2} - 1 : (a + 1) (a - 1)

= (a + 2) (a + 1) (a - 1)
