Step-by-step explanation:
I am not sure what exactly you mean.
do you mean the complete square of an expression or
term ?
if so, then by multiplying this term by itself, and that means in general, every part is multiplied by every part and the part results are added considering the signs involved.
e.g.
squaring a+b
(a+b)(a+b) = a×a + a×b + b×a + b×b = a² + 2ab + b²
remember that multiplication and addition are commutative (you can flip the right and left sides with each other and still get the same result : a+b = b+a, a×b = b×a).
squaring a-b
(a-b)(a-b) = a×a + a×-b + -b×a + -b×-b = a² - 2ab + b²
remember that
+×- = -×+ = -
-×- = +
+×+ = +
a more complex example ?
squaring a-b+c
(a-b+c)(a-b+c) =
= a×a + a×-b + a×c + -b×a + -b×-b + -b×c + c×a + c×-b + c×c =
= a² - 2ab - 2bc + 2ac + b² + c²
The dividend on £1 is 15 p. Therefore, the dividend on £320.80 or 32080 pence (320.80 * 100) will be (32080*15)pence or 4812 pence, which is £48.12 (4812/100).
Answer:
Amount to be kept separately for having $17,000 at year end = $16,715.83
Step-by-step explanation:
As it is provided, that annual return = 1.7% compounded annually.
We need to calculate the amount to be invested today, to get a total of $17,000 at year end.
Since the interest is compounded annually, it is a simple interest if the term is of 1 year.
Therefore,
Investment + Investment 
1.7% = $17,000
Investment + 0.017 Investment = $17,000
1.017 Investment = $17,000
Investment = 
Therefore, Investment today = $16,715.83
