simplify (x-3-sqrt(5))(x-3+sqrt(5))

simplify

(x - 3 - 5) (x - 3 + 5)

x^{2} - 6 x + 4

Solution steps

(x - 3 - 5) (x - 3 + 5)

Distribute parentheses

= xx + x (- 3) + x 5 - 3 x - 3 (- 3) - 35 - 5 x - 5 (- 3) - 55

Simplify

xx + x (- 3) + x 5 - 3 x - 3 (- 3) - 35 - 5 x - 5 (- 3) - 55 : x^{2} - 6 x + 4

= x^{2} - 6 x + 4

(a + b) \cdot (a - b)

(3 - x) e^{x}

(e^{- 2 s + 2} - 1) (- 1 - s) - (e^{- 2 s - 2}) (1 - s)

\frac{6 x}{( x - 1 ) ^{4}}

\frac{- 1 - 3 x}{2 ( - 2 + x )}
