化简 t^2\H(t-4)dt

解答

化简

t^{2} H (t - 4) d t

t^{2} H (t - 4) d t

求解步骤

t^{2} H (t - 4) d t

无法进一步化简

= t^{2} H (t - 4) d t

e x p an d x^{(a - b) (a^{2} + ab + b^{2})}

e x p an d \frac{( x + 3 ) ( x - 2 )}{( x + 1 ) ( x - 4 )}

e x p an d \frac{9 ( 1 - 40 b - 56 c )}{8}

e x p an d π (2 x + π)^{2}

e x p an d \frac{8}{( 3 x - 4 ) ^{2}}
