Step-by-step explanation:

Question No.11.(a) Explanation :

$( {x}^{3} + 1) \div (x + 1) \\ = {(x + 1)( {x}^{2} - x + 1)} \div (x + 1) \\ = ( {x}^{2} - x + 1) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Question No.11(b) Explanation :

$( {x}^{2}y - 3xy) \div y \\ = {x}^{2} - 3x \: \: \: \: \: \: \: \: \: \: \:$
