factor x^4-19x^2+48

Solution

factor

x^{4} - 19 x^{2} + 48

Solution

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

Solution steps

x^{4} - 19 x^{2} + 48

Let

u = x^{2}

= u^{2} - 19 u + 48

Factor

u^{2} - 19 u + 48 : (u - 3) (u - 16)

= (u - 3) (u - 16)

Substitute back

u = x^{2}

= (x^{2} - 3) (x^{2} - 16)

Factor

x^{2} - 16 : (x + 4) (x - 4)

= (x^{2} - 3) (x + 4) (x - 4)
