expand cos(x)(4cos^2(x)-3)

expand

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

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

Solution steps

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

Simplify

cos (x) \cdot 4 cos^{2} (x) - cos (x) \cdot 3 : 4 cos^{3} (x) - 3 cos (x)

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

40 (\frac{3}{8} x - \frac{2}{5} = \frac{7}{4})

6 x - 3 - 3 (x + 2)

\frac{y ^{3} - 6 y + 8}{y}

A (- 6, 0) B (0, - 2)

x^{2} \cdot (100 x - 300 = 200)
