a.
Answer to Problem 4P
Explanation of Solution
Given:The expression is
Calculation:difference in square formula is givenby
b.
To show: The characteristics that make the above calculation possible.
b.
Explanation of Solution
Given:The binomial given
Reason:According to the difference between square theorem the quadratic equation may be written as a difference between the two squares such that it is factorize into two binomials where one is the sum and other is the difference of the roots of the squares. This theorem can be used
until there is a difference between the squares.
Here in the above equation 64 is the square of 8 while 25 is the square of 5same with the case of d but instead of difference there is the addition between the two squares.
Hence this characteristic makes the above solution not possible by difference between square theorem.
