71701,71702, 71703 etc

Step-by-step explanation:

Given :

$7.17$ × $10^{4}$ and 8.17× $10^{5}$

Now

$7.17$ × $10^{4}$ =71700 and

8.17× $10^{5}$ =817000

There are so many numbers between 71700 and 817000

Which will result in a difference of squares?

otez555 [7]

Expanding the given expressions using Foil:

1)(–7x + 4)(–7x + 4) = $7x^{2}-28x-28x+16=49x^{2}-56x+16$

2) (–7x + 4)(4 – 7x)= $-28x+49x^{2}+16-28x=49x^{2}-56x+16.$

3)(–7x + 4)(–7x – 4)= $49x^{2}+28x-28x-16$ = $49x^{2}-16.$

4)(–7x + 4)(7x – 4)= $49x^{2}+28x+28x-16=49x^{2}+56x-16.$

The third option that is (–7x + 4)(–7x – 4) is difference of two squares.
