factor x^4-625

factor

x^{4} - 625

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

Solution steps

x^{4} - 625

Apply exponent rules

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

Apply Difference of Two Squares Formula:

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

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

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

Factor

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

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

\frac{66}{6}

n^{2} - 28 = 0

\frac{12 !}{6 ! \cdot 6 !}

x + 1 = 7 x - 5

(\frac{7}{8})^{- 1}
