factor z^2-2-20

factor

z^{2} - 2 - 20

(z + 22) (z - 22)

Solution steps

z^{2} - 2 - 20

Subtract the numbers:

- 2 - 20 = - 22

= z^{2} - 22

Apply radical rule:

a = (a)^{2}

22 = (22)^{2}

= z^{2} - (22)^{2}

Apply Difference of Two Squares Formula:

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

z^{2} - (22)^{2} = (z + 22) (z - 22)

= (z + 22) (z - 22)

- 4 (1 - 8 n)^{'} - 4 (8 n + 4)^{'}

5 a - 5 b - 2 b x + 2 a x

6 e^{2} - 13 e + 6

(x - 7) - (2 x - 4)^{'}

d (x^{2} y)
