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

simplify

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

(x - 3) (x^{2} - 6 x + 4)

Solution steps

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

Distribute parentheses

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

Simplify

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

= (x - 3) (x^{2} - 6 x + 4)

(1 + 3 z + z^{3})^{6}

10 (- 2 e^{- 2 x} cos^{2} (x) - e^{- 2 x} sin (2 x))

(x + δ x)^{2}

(x + δ x)^{5}

(x + δ x)^{4}
