factor (x^2+2x)-1

factor

(x^{2} + 2 x) - 1

(x + 1 - 2) (x + 1 + 2)

Solution steps

(x^{2} + 2 x) - 1

Remove parentheses:

(a) = a

= x^{2} + 2 x - 1

Solve

x^{2} + 2 x - 1 = 0 : x = - 1 + 2, x = - 1 - 2

Polynom can therefore be factored into

= (x - (- 1 + 2)) (x - (- 1 - 2))

Refine

= (x + 1 - 2) (x + 1 + 2)

4 x^{2} + 36 + 81

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

4 sin (14 x - 20)

3 cos (100 x + 3) + 4 cos (100 x + 4)

x^{5} + x \frac{d}{d x} (7)
