We can first factor the numerator :
We also know that
We can thus factor
-
a²=m²
Socolor(red)(a=m -
-2ab=-6m
Thus2ab=6m ( we multiply by-1 on both side )
ab=3m ( we divide by2 on both side )
m*b=3*m ( sincecolor(red)(a=m )
cancelm*b=3*cancelm
color(blue)(b=3 -
9=b²
Socolor(blue)(b=3 : What we found, perfect.
Thus :
And thus :
