so can anyone help me with these factorisation questions?
factorise
18t^2 -2
3tx-2sx+15ty-10sy
can anyone please show me the steps thx
factorise
18t^2 -2
3tx-2sx+15ty-10sy
can anyone please show me the steps thx
Firstly note that there are 2 terms. 18t^2 and -2. These are both divisible by 2, so take a 2 to the front of the brackets and write it like:roxas said:18t^2 -2
You can write this as x(3t-2s)+5y(3t-2s) by simply taking the x and y terms out of each individual term. Now note that each set of brackets is the same so it can be furthermore factorised to: (3t-2s)(x+5y)roxas said:3tx-2sx+15ty-10sy
Do you want to bet on that?PotatoSalad said:Firstly note that there are 2 terms. 18t^2 and -2. These are both divisible by 2, so take a 2 to the front of the brackets and write it like:
2(9t^2 -1)
This will not factorise any further.

There could be various reasons why you may struggle with math. It could be due to a lack of understanding of the basic concepts, a fear of failure, or a lack of interest. It is important to identify the root cause of the struggle in order to find ways to improve in math.
Yes, it is normal to struggle with math. Just like any other subject, some people may find math more challenging than others. It is important to remember that everyone has their strengths and weaknesses, and with practice and determination, anyone can improve in math.
There are various ways to improve in math. Some suggestions include seeking help from a tutor, practicing regularly, breaking down problems into smaller steps, and seeking clarification when needed.
