factor y^4-625

factor

y^{4} - 625

(y^{2} + 25) (y + 5) (y - 5)

Solution steps

y^{4} - 625

Apply exponent rules

= (y^{2})^{2} - 2 5^{2}

Apply Difference of Two Squares Formula:

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

(y^{2})^{2} - 2 5^{2} = (y^{2} + 25) (y^{2} - 25)

= (y^{2} + 25) (y^{2} - 25)

Factor

y^{2} - 25 : (y + 5) (y - 5)

= (y^{2} + 25) (y + 5) (y - 5)

(5)^{0}

(5 - i) + (8 + 10 i)
