化简 (sqrt(x)+3sqrt(2))(sqrt(x)-3sqrt(2))

解答

化简

(x + 32) (x - 32)

x - 18

求解步骤

(x + 32) (x - 32)

Apply Difference of Two Squares

(x + 32) (x - 32) : x - 18

= x - 18

e x p an d (sin^{6} (x) + cos^{6} (x) - 1) (sec^{2} (x) + csc^{2} (x))

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

e x p an d \frac{1}{t ( t + 1 )}

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

e x p an d (x + 1) d x
