factor 3cos^2(x)+cos(x)-4

factor

3 cos^{2} (x) + cos (x) - 4

(cos (x) - 1) (3 cos (x) + 4)

Solution steps

3 cos^{2} (x) + cos (x) - 4

Break the expression into groups

= (3 cos^{2} (x) - 3 cos (x)) + (4 cos (x) - 4)

Factor out

3 cos (x)

from

3 cos^{2} (x) - 3 cos (x) : 3 cos (x) (cos (x) - 1)

Factor out

4

from

4 cos (x) - 4 : 4 (cos (x) - 1)

= 3 cos (x) (cos (x) - 1) + 4 (cos (x) - 1)

Factor out common term

cos (x) - 1

= (cos (x) - 1) (3 cos (x) + 4)

(x^{3} + 2 x) + (- x^{2} + 4)

ab c - 2 ab cz - x y + 2 x yz

\frac{x + 4}{x ^{2} + 8 x + 16}

x^{2} 11 x^{24}

e^{I n (x)}
