化简 (5sqrt(c)+sqrt(d))(5sqrt(c)-sqrt(d))

解答

化简

(5 c + d) (5 c - d)

25 c - d

求解步骤

(5 c + d) (5 c - d)

Apply Difference of Two Squares

(5 c + d) (5 c - d) : 25 c - d

= 25 c - d

s im pl i f y (k + i + j) \times (k + ki + i + ij + j)^{2}

e x p an d \frac{s}{( s ^{2} + 4 ) ( s ^{2} + w ^{2} )}

e x p an d 5 e^{x} tan (d) x + (1 - e^{x}) sec^{2} (x)

e x p an d (1 - L) \cdot (1 - t)

e x p an d \frac{3 ( 3 + j w )}{( 2 + j w ) ( 4 + j w )}
