-70y^2+90x^3+100yx^2-63xyfactor by grouping

The idea of grouping is to get the terms in groups that allow you to factor out from each group something that becomes a factor in itself, leaving two factors behind that are alike. Like this: rearrange those terms so they are in this order:
(-70y^2 - 63xy) + (90x^3 + 100yx^2).  Now out of the first set we are going to factor out a -7y, and out of the second set we are going to factor out a 10x^2. When we do this, this is what we get: -7y(10y + 9x) + 10x^2(9x + 10y). As you can see, what's inside both sets of parenthesis is the same, just in a different order. We can factor that out now, leaving (9x + 10y)(10x^2 - 7y). And that is factored by grouping.

Use Liam DeWitt's Flash Card statement and the credit calendar for Exercises a-e.

The answers for this task are gotten in most cases by Careful Observation of Liam DeWitt's Bank Account Information.

<h3>What is a Bank Account Information?</h3>

A bank account information refers to all the details present on or which can be deduced from one's statement or record of banking activities..

Liam's Average Daily Balance is: Total sum of balance each day divided by the number of days. That is
(250+87+1300+470-200+34.76+102.71+45.90+84.60)/9

ADB= $241.66

B) Liam's Monthly Periodic Rate (MPR) is the Annual Interest Rate divided by the number of periods. In this case, that will be:

19.8%/12

MPR = 1.65%

C) Liam's Finance Charge is (Average Daily Balance * APR)/365.

That is (241.66 * 19.8)/365 = 13.11%

D) Liam's New Balance is calculated by removing new inflow from old balance. That is

(250+87.60+1,300+470.63+34.76+102.71+45+848.60)-3,240.5

= $-101.20

E) Liam's Available Line of Credit is clearly stated as $4,000.
