factor

z^{2} - 1

Solution

(z + 1) (z - 1)

Solution steps

z^{2} - 1

Rewrite

1

as

1^{2}

= z^{2} - 1^{2}

Apply Difference of Two Squares Formula:

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

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

= (z + 1) (z - 1)

Popular Examples

x^{2} < x + 30

simplify 1/3+1/2-1/9 simplify

\frac{1}{3} + \frac{1}{2} - \frac{1}{9}

m^{2} - 14 m + 49 = 0

-(x-2)/3-(x-1)/4 >(x-3)/2-1

- \frac{x - 2}{3} - \frac{x - 1}{4} > \frac{x - 3}{2} - 1

simplify-2/((1/9)^{3/2)}simplify

- \frac{2}{( \frac{1}{9} ) ^{\frac{3}{2}}}
