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)

∣ r ∣ - 3 > 2

\frac{2 ( 4 )}{4 + 4}

4 x^{2} + 5 x - 21

\frac{π}{2} < θ < \frac{3 π}{4}

(f \cdot g) (1)
