化简 f(x/2-3)-4

解答

化简

f (\frac{x}{2} - 3) - 4

\frac{f ( - 6 + x )}{2} - 4

求解步骤

f (\frac{x}{2} - 3) - 4

合并

\frac{x}{2} - 3 : \frac{- 6 + x}{2}

= f \frac{- 6 + x}{2} - 4

化简

f \frac{- 6 + x}{2} : \frac{f ( - 6 + x )}{2}

= \frac{f ( - 6 + x )}{2} - 4

e x p an d (\frac{1}{2} - b)^{2}

e x p an d \frac{- 3 x + 2}{3 ( 3 x - 1 )}

e x p an d (10 sin (θ) - 3)^{2}

e x p an d ((2 (t^{2} + 1)^{2}), - t (t^{2} + 1)) \cdot (1, 2 t)

e x p an d \frac{- x ^{2} - 3 x - 10}{( x + 2 ) ( x + 4 ) ( x - 2 )}
