First you want to find a square number that is a factor of 75. In this case it is 25, as 25 x 3 = 75 . With this information you can expand the surd into:sqrt(25) x sqrt(3)
As 5^2 = 25, this can beco...

b/a = -6 / 2 = -3 .........a - b = 2 - (-6) = 8 ............ab = 2 x -6 = -12 ...............Therefore ab, -12, has the smallest value.

First, you need to look at the x² term and the number 10 - find all the factors of these numbersThe number before x² is 1, and since 1 is a prime number, the only factor is 1. 1=1x1A...
