Why bother with a post grad course - waste of time? 17-10-2016
1. I need help with these two questions, what are the steps to solve it?

Part (a) is just substituting values into the formula.

You started off correctly so there was no need to scribble out your working For part a, substitute in the given values into the equation and then simplify it so that you have one value for y
4. For the second part get everything except x^2 onto one side of the equation then square root both sides by removing the ^2 sign fro the x and putting a square root sign over the other side of the equation. I think, I don't know for sure sorry

I'm stuck on the (2qx^2) part of the question

I'm stuck on the (2qx^2) part of the question
7. 1. Y= (-10) - (2x3x25) = -160
2. Y=p-2qx^2
Y-P=-2qx^2
(Y-P)/(-2q) = x^2
X= sqrt((Y-P)/(-2q))

I'm stuck on the (2qx^2) part of the question
so you are given that:
p = -10
q= 3
x= -5

2qx^2 = 2 * q * x^2
9. I hope you aren't doing the exam tomorrow - this is wrong!!
10. That's wrong...you can't divide by p-2q.

I'm stuck on the (2qx^2) part of the question
This means 2 multiplied by q multiplied by x multiplied by x
12. (Original post by surina16)
so you are given that:
p = -10
q= 3
x= -5

2qx^2 = 2 * q * x^2
Delete the rest please - full solutions are not allowed.

sorry

For that part you need divide 2q on both sides and then square root both sides to get the square off
15. Good luck n all the best if you have GCSE maths tomorrow
16. these type of Questions they are very easy, how can you not answering them ?

I'm sorry I'm not as educated as you but I have had to teach my self Single & Additional science, Religious studies, History, Higher English and Higher Maths all by myself in less than a year because of complications with school.

Some people find different things hard, so rather than criticising and being all boastful about yourself help the guy out
