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

expand

(2 cos (x) - 2) (cos (x) - 3)

2 cos^{2} (x) - 8 cos (x) + 6

Solution steps

(2 cos (x) - 2) (cos (x) - 3)

Apply FOIL method

(2 cos (x) - 2) (cos (x) - 3) : 2 cos^{2} (x) - 8 cos (x) + 6

= 2 cos^{2} (x) - 8 cos (x) + 6

x^{(\frac{1}{3})} \cdot (x - 4)

\frac{( 25.5 \cdot s + 121 )}{( ( s ^{2} + 17.2 ) \cdot ( s + 6.24 ) )}

\frac{y ^{2}}{4 y}

(- \frac{3}{2} x + b)^{2}

\frac{d ^{2}}{d x ^{2}} ((y (t, x)) (t^{3} + t))
