factor x^2-2-15

factor

x^{2} - 2 - 15

(x + 17) (x - 17)

Solution steps

x^{2} - 2 - 15

Subtract the numbers:

- 2 - 15 = - 17

= x^{2} - 17

Apply radical rule:

a = (a)^{2}

17 = (17)^{2}

= x^{2} - (17)^{2}

Apply Difference of Two Squares Formula:

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

x^{2} - (17)^{2} = (x + 17) (x - 17)

= (x + 17) (x - 17)

- 40 x^{4 - 16 x^{2}}

x^{2 - 4 x y + 4 y^{2}}

cos (π + 2 πn)

(x y - 2 x + 4 y - 8) d y

\frac{2 x - 4}{4 x}
