factor 2x^2+(-1)

factor

2 x^{2} + (- 1)

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

Solution steps

2 x^{2} + (- 1)

Rewrite

2 x^{2} + (- 1)

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

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

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

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

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

(\cdot (- y)) 2

in t (2 x)

(3 x) (ln (sec (x^{2})))

x^{6} + 1 x^{3} - 20

e^{x} cos (y) d x - e^{x} sin (y) d y
