factor 2cos^2(x)+cos(x)-1

factor

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

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

Solution steps

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

Break the expression into groups

= (2 cos^{2} (x) - cos (x)) + (2 cos (x) - 1)

Factor out

cos (x)

from

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

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

Factor out common term

2 cos (x) - 1

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

2 u + a u - 2 u - a u

\frac{30}{42}

5 x + (- 7)

\frac{d}{d t} ((x) (- x t))

\frac{x + 5}{x ^{3} + 125}
