(m3 - 6m2 - 16m + 63) divided by (m - 7)

Arlecino [84]

Therefore( $m^3 -6m^2-16m +63$ )÷ (m-7) $= (m^2 +m-9)$

Step-by-step explanation:

$m^3 -6m^2-16m +63$

$=m^3 -7m^2$ $+m^2 -7m$ $-9m+63$

$= m^2(m-7)$ $+m(m-7)$ $-9(m-7)$

$= (m-7 ) (m^2 +m-9)$

Therefore( $m^3 -6m^2-16m +63$ )÷ (m-7) $= (m^2 +m-9)$
