factor 7x^4-12x^2-4

Solution

factor

7 x^{4} - 12 x^{2} - 4

Solution

(7 x^{2} + 2) (x^{2} - 2)

Solution steps

7 x^{4} - 12 x^{2} - 4

Let

u = x^{2}

= 7 u^{2} - 12 u - 4

Factor

7 u^{2} - 12 u - 4 : (7 u + 2) (u - 2)

= (7 u + 2) (u - 2)

Substitute back

u = x^{2}

= (7 x^{2} + 2) (x^{2} - 2)
