Hi guys look at question (b), can you tell me the basics of doing this problem and how to solve it? I remembered I learned it for the past two years but around 8 months ago I stopped studying maths.

So what prompts you to try these problems now?

Hint for #1(a)

Use PEMDAS (Hierarchy of mathematical expressions) and do the mathematical operations.

I stopped because I just finished graduating from high school, will post the working later..
 
The expression is \(\displaystyle \frac{3}{m^2- m}- \frac{4}{m- 1}\) so this is "subtracting fractions" problem. You need to get the "least common denominator". \(\displaystyle m^2- m= m(m- 1)\) so to get the least common denominator, multiply the numerator and denominator of the second fraction by m.

What's that "(17)" mean in question (a) (1)? I'm in UK and we might be a bit behind the times. We still use Pythagoras over here!

9(17) = 9 * 17 = 153

Pythagoras is used every where - since 500 B.C.
