 Hello and welcome to the session. Today I'll help you with the following question. The question says find and correct the error in the following mathematical statement. Let's move on to the solution. The given statement is a plus 4 multiplied by a plus 2 is equal to a square plus 8. Consider the left hand side of this given statement. That is a plus 4 multiplied by a plus 2. We shall use the distributive law here. According to the distributive law we have a multiplied by b plus c is equal to a multiplied by b plus a multiplied by c. That is the term outside the bracket is multiplied by each and every term inside the bracket. When we apply the distributive law here we get this becomes equal to a plus 4 multiplied by a that is the first term of the second bracket plus multiplied by 2. That is the second term of the second bracket. Also according to the commutative law we have a multiplied by b is equal to b multiplied by a. So on applying the commutative law here we get a multiplied by a multiplied by a plus 4. Again we will apply the distributive law so this becomes equal to a multiplied by a plus a multiplied by 4 times equal to a so on the right hand side. So this is the error in the session. Have a good day.
