factor 4x^4-5x^2-9

Solution

factor

4 x^{4} - 5 x^{2} - 9

Solution

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

Solution steps

4 x^{4} - 5 x^{2} - 9

Let

u = x^{2}

= 4 u^{2} - 5 u - 9

Factor

4 u^{2} - 5 u - 9 : (u + 1) (4 u - 9)

= (u + 1) (4 u - 9)

Substitute back

u = x^{2}

= (x^{2} + 1) (4 x^{2} - 9)

Factor

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

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