Explanation:
One way is to use the divisor as a factor in the numerator.
#"Consider the numerator"#
#color(red)(h^2)(2h+3)color(magenta)(-3h^2)-5h^2+22h#
#=color(red)(h^2)(2h+3)color(red)(-4h)(2h+3)color(magenta)(+12h)+22h#
#=color(red)(h^2)(2h+3)color(red)(-4h)(2h+3)color(red)(+16)(2h+3)color(magenta)(-48#
#rArr"quotient "=color(red)(h^2-4h+16)" and remainder " =color(magenta)(-48)#
#rArr(2h^3-5h^2+22h)/(2h+3)=h^2-4h+16-48/(2h+3)#
