factor 2x^4-17x^2-9

Solution

factor

2 x^{4} - 17 x^{2} - 9

Solution

(2 x^{2} + 1) (x + 3) (x - 3)

Solution steps

2 x^{4} - 17 x^{2} - 9

Let

u = x^{2}

= 2 u^{2} - 17 u - 9

Factor

2 u^{2} - 17 u - 9 : (2 u + 1) (u - 9)

= (2 u + 1) (u - 9)

Substitute back

u = x^{2}

= (2 x^{2} + 1) (x^{2} - 9)

Factor

x^{2} - 9 : (x + 3) (x - 3)

= (2 x^{2} + 1) (x + 3) (x - 3)
