simplify (sqrt(x)-sqrt(4-x))*(sqrt(x)+sqrt(4-x))

simplify

(x - 4 - x) \cdot (x + 4 - x)

2 x - 4

Solution steps

(x - 4 - x) (x + 4 - x)

Apply Difference of Two Squares

(x - 4 - x) (x + 4 - x) : 2 x - 4

= 2 x - 4

e^{4 t} \cdot (3 e^{- 4 t} + 2 e^{- 6 t})

\frac{d}{d t} ((x) (k (a - x) (b - x)))

2 (4 + 510)

(0.01515 + 0.216 i) \cdot (81, 68 - 3811 i)

3 (705 x^{2} - 4814 x + 729)
