Maths help

Now you divide each part of the top fraction by 2 which will get rid of the 2 on the bottom of the fraction and voila, you have your answer!

For 8$\sqrt{2}$ , you just cancel the 8 and keep the root 2 as it is.

But its not in the form :/

Divide EACH part. so the 8 $\sqrt{2}$ AND the 6.

It doesn't matter if there's a minus instead of the positive.
You can rearrange to get it in the form a+b$\sqrt{2}$
You still have the answer in the form it's asking you.

8/2= 4
6/2=3

I want to make sure you know why you cancel all the terms on the top though instead of just the one that you did initially.

When you have multiple terms on the top and one term on the bottom of the fraction, if you want to cancel the whole fraction you need to make sure you can cancel ALL the terms on the top with the one on the bottom. It's because you can split the fraction up into single fractions.

Does anyone know how to do this

Construct is just another way of telling you to make/build/draw.

So you just need to get a compass and make sure the centre line is at point P.
Mark where the compass tells you is 30 degrees and draw a straight line from P through the point you marked as 30 degrees.

Hint : an equilateral triangle has angles of 60^o

I think you're getting mixed up with 'compass' and 'protractor'.

Ive never done this topic any videos or explanation?

oh my, fml. That is embarassing, haha.

I'm just gonna shut up.
I know I seem like I don't know what I'm talking about but I did get an A* for Maths GCSE and I'm taking it for A levels, aiming for A/A* (dunno how I deserve it tbh)

I feel like I need to justify myself aha.
Sorry OP my lack of sleep and attention is not helping you at all. I'm gonna refrain from answering.

Do you know about constructions? How to construct a triangle with given lengths, an angle bisector and a perpendicular bisector?

I need to know what you know before I can recommend how to help.

Nop.

Here's a video showing the three constructions that you'll need for GCSE. You'll need to practice them with a ruler and a compass.

For your question, the first step is to construct an equilateral triangle.
