factor y^4-121

Solution

factor

y^{4} - 121

Solution

(y^{2} + 11) (y^{2} - 11)

Solution steps

y^{4} - 121

Apply exponent rules

= (y^{2})^{2} - 1 1^{2}

Apply Difference of Two Squares Formula:

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

(y^{2})^{2} - 1 1^{2} = (y^{2} + 11) (y^{2} - 11)

= (y^{2} + 11) (y^{2} - 11)
