Substitute 2 for x, 3 for f(2). This gives you an equation with a as an unknown
3=a*(2^2)-6(2)-7
3=4a-12-7
4a=3+12+7=22 or a=22/4=11/2
Check
11/2*4-12-7=3 Checks OK

### Simplify and ratio

A ratio is a division of two quantities that may or may not have the same units. Example of a ratio: Speed =distance/time, specific gravity (density) =mass/volume.

Simplifying a fraction is writing it with the smallest numerator and denominator. In that case one says that the fraction is in its reduced form.
35/20=(5*7)/(5*4)=(5/5)*(7/4)=7/4
7/4 cannot be reduced further, so we say the reduced form of 35/20 is 7/4

### Can anyone help me to solve this problem? 11^23 mod 187

One way to do this is to simplify it piece by piece. We know 11^23 = 11 * 11 * 11 * 11^20, and we know
that 11 * 11 * 11 = 1331 in to find this modulo 187 we look at 1331/187 which is > 7, so we can take 1331 - 7 * 187
which is 22. So 11^3 mod 187 is 22. we can simplify 11 ^23 = ( 11^3 ) * 7 * 11^2 because we know 11^3 = 22
we can write this as 22 * 7 * 11^2. and 11^2 mod 187 is 121 so now have a number to modulo.
11*7*121 mod 187 = 9317 mod 187 this is 88. Hope this helps you understand simplifying.

### I cannot find a driver or SW package for Windows 7.

I have the same problem. This is what Tripp Lite told me: "We have tested the existing drivers for the US-4A on both Windows 7 and Mac OS 10.6.2. Neither Windows7 nor Mac OS 10.6.2 functioned with the USB server products (US-4A and U2S-2A) while utilizing current drivers. I suspect that this is due to the fact that both OS' appear to have undertaken a major overhaul over their prior counterparts (XP, Vista, 10.5.X). In order for functionality to exist between the operating systems (in this case Win 7 and Mac OS 10.6.X) new drivers would need to be released. At this point, there is no plan to move forward with drivers to accommodate these operating systems."

I told them I was not impressed and that this lack of support would affect any future purchases of thier products.

### 2/(x+1)+3/(x+2)

(5x+7)/(x^2+3x+2)

is the simplified answer because you can't break up the polynomials. The polynomials are like groups and you can't break them apart unless the polynomial itself can be simplified like

2x+4

can be simplified to 2(x+2)

so in which case you could simplify the problem down further.
