factor m^4-81

Solution

factor

m^{4} - 81

Solution

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

Solution steps

m^{4} - 81

Apply exponent rules

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

Apply Difference of Two Squares Formula:

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

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

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

Factor

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

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