Answer:
• The distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation.
Step-by-step explanation:
We have to multiply the term b2/4a2 by a in order to determine the value to add to the left side of the equation so as to balance both sides of the equation.
If we multiply the terms, we get;
Therefore, we shall be adding the term to the left side of the equation.

Answer:
The fraction of the students who failed to went partying =
Step-by-step explanation:
Let total number of students = 100
No. of students partied are twice the no. of students who not partied.
⇒ No. of students partied = 2 × the no. of students who are not partied
No. of students partied before the exam = 20 % of total students
⇒ No. of students partied before the exam = × 100
⇒ No. of students partied before the exam = 20
No. of students who not partied before the exam =
Thus the fraction of the students who failed to went partying =
