factor cos^2(x)+3cos(x)+2

factor

cos^{2} (x) + 3 cos (x) + 2

(cos (x) + 1) (cos (x) + 2)

Solution steps

cos^{2} (x) + 3 cos (x) + 2

Break the expression into groups

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

Factor out

cos (x)

from

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

Factor out

2

from

2 cos (x) + 2 : 2 (cos (x) + 1)

= cos (x) (cos (x) + 1) + 2 (cos (x) + 1)

Factor out common term

cos (x) + 1

= (cos (x) + 1) (cos (x) + 2)
