factor m^3-3m-2

Solution

factor

m^{3} - 3 m - 2

Solution

(m + 1)^{2} (m - 2)

Solution steps

m^{3} - 3 m - 2

Use the rational root theorem

= (m + 1) \frac{m ^{3} - 3 m - 2}{m + 1}

\frac{m ^{3} - 3 m - 2}{m + 1} = m^{2} - m - 2

= (m + 1) (m^{2} - m - 2)

Factor

m^{2} - m - 2 : (m + 1) (m - 2)

= (m + 1) (m + 1) (m - 2)

Apply exponent rule:

aa = a^{2}

(m + 1) (m + 1) = (m + 1)^{2}

= (m + 1)^{2} (m - 2)
