(x² + 3x - 1)(2x² - 2x + 1)
x²(2x² - 2x + 1) + 3x(2x² -2x + 1) -1(2x² - 2x + 1)
2x^4 - 2x³ + x² + 6x³ - 6x² + 3x - 2x² + 2x - 1
2x^4 - 2x³ + 6x³ + x² - 6x² - 2x² + 3x + 2x - 1
2x^4 + 4x³ - 7x² + 5x - 1
<span>(D)The result 2x4 + 4x3 − 7x2 + 5x − 1 is a polynomial.</span>

Answer:
The new mortgage repayment is $10,580.69
Step-by-step explanation:
As at the time Douglas lost his job,he has already made repayments on the mortgage for a period of 7 years,by extending the repayment period by another 7 years,Douglas now have a period of repayment of 30 years now(30-7+7).
The new repayment yearly can be computed using the pmt formula in excel as given below:
=pmt(rate,nper,-pv,fv)
rate is the interest rate on mortgage given as 4.25%
nper is the period of repayment now 30 years
pv is the current of balance of $177,533.62
fv is the total amount repayable on the mortgage and it is not known hence taken as zero
=pmt(4.25%,30,-177533.62,0)=$10,580.69
