factor 3x^4+14x^2-5

Solution

factor

3 x^{4} + 14 x^{2} - 5

Solution

(3 x^{2} - 1) (x^{2} + 5)

Solution steps

3 x^{4} + 14 x^{2} - 5

Let

u = x^{2}

= 3 u^{2} + 14 u - 5

Factor

3 u^{2} + 14 u - 5 : (3 u - 1) (u + 5)

= (3 u - 1) (u + 5)

Substitute back

u = x^{2}

= (3 x^{2} - 1) (x^{2} + 5)
