Explanation:
#"one way is to use the divisor as a factor in the numerator"#
#"consider the numerator"#
#color(red)(3v^2)(v+2)color(magenta)(-6v^2)+12v^2+10v-6#
#=color(red)(3v^2)(v+2)color(red)(+6v)(v+2)color(magenta)(-12v)+10v-6#
#=color(red)(3v^2)(v+2)color(red)(+6v)(v+2)color(red)(-2)(v+2)color(magenta)(+4)-6#
#=color(red)(3v^2)(v+2)color(red)(+6v)(v+2)color(red)(-2)(v+2)-2#
#"quotient "=color(red)(3v^2+6v-2)," remainder "=-2#
#rArr(3v^3+12v^2+10v-6)/(v+2)#
#=3v^2+6v-2-2/(v+2)#
