factor x^4-50x^2+49

Solution

factor

x^{4} - 50 x^{2} + 49

Solution

(x + 1) (x - 1) (x + 7) (x - 7)

Solution steps

x^{4} - 50 x^{2} + 49

Let

u = x^{2}

= u^{2} - 50 u + 49

Factor

u^{2} - 50 u + 49 : (u - 1) (u - 49)

= (u - 1) (u - 49)

Substitute back

u = x^{2}

= (x^{2} - 1) (x^{2} - 49)

Factor

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

= (x + 1) (x - 1) (x^{2} - 49)

Factor

x^{2} - 49 : (x + 7) (x - 7)

= (x + 1) (x - 1) (x + 7) (x - 7)
