factor y^4-49

Solution

factor

y^{4} - 49

Solution

(y^{2} + 7) (y^{2} - 7)

Solution steps

y^{4} - 49

Apply exponent rules

= (y^{2})^{2} - 7^{2}

Apply Difference of Two Squares Formula:

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

(y^{2})^{2} - 7^{2} = (y^{2} + 7) (y^{2} - 7)

= (y^{2} + 7) (y^{2} - 7)
