factor y^4-81

Solution

factor

y^{4} - 81

Solution

(y^{2} + 9) (y + 3) (y - 3)

Solution steps

y^{4} - 81

Apply exponent rules

= (y^{2})^{2} - 9^{2}

Apply Difference of Two Squares Formula:

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

(y^{2})^{2} - 9^{2} = (y^{2} + 9) (y^{2} - 9)

= (y^{2} + 9) (y^{2} - 9)

Factor

y^{2} - 9 : (y + 3) (y - 3)

= (y^{2} + 9) (y + 3) (y - 3)
