化简 2*\delta(x-4)+7\H(x-11)

解答

化简

2 \cdot δ (x - 4) + 7 H (x - 11)

2 δ (x - 4) + 7 H (x - 11)

求解步骤

2 δ (x - 4) + 7 H (x - 11)

无法进一步化简

= 2 δ (x - 4) + 7 H (x - 11)

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

e x p an d ((t - 1)^{2}, t^{2} - 3 t + 2) \cdot (- 1, - 1)

e x p an d 9 x^{2} - 12 x + \frac{4}{3} x - 1

e x p an d \frac{( 37 - 11 x )}{( ( x + 1 ) ( x - 2 ) ( x - 3 ) )}

e x p an d \frac{2 ( 105 - 3 y )}{5}
