Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. n2+5/2n

Step-by-step explanation:

Given

Required

(a) Make a perfect square trinomial

(b) Write as binomial square

Solving (a)

Let the missing part of the expression be k;

This gives

To solve for k, we need to square half the coefficient of n;

i.e. Since the coefficient of n is , then

Hence;

=

Solving (b)

Expand

Factorize

Hence:

=

answer: give more info

step-by-step explanation:

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
