I am a Computer Science undergraduate studying at Durham University. I am very enthusiastic about the understanding of scientific concepts and also the core ideas and building blocks of subjects. I have been tutoring during my time at university through volunteering at the Durham University SCA and have really enjoyed the experience and would love to continue helping others.
In the sessions, I will focus on the areas that you will not have covered before or that you have been finding difficulties in. However, in general the topics that I will go through will be completely based on what you would want/need!
I'd like to go through topics quite thoroughly, making sure that you fully understand the concepts behind them. I have found this to be beneficial in exam situations where they throw questions that are different to the standard questions you will have normally seen, having a proper understanding will allow you to assess these questions calmly!
Finally, I would love for you to have fun in these sessions, hopefully enjoying the subject as much as I have, especially when coming up to a hurdle with a topic you don't understand and having it slowly clear up for you. It's a great feeling!
If you would like to ask me any questions, or would like book a session just let me know through the website!
Thank you and I look forward to seeing you!

To solve this equation we have two different methods:
1) We can solve this method 'by hand' and is done by knowing how to factorise the quadratic and is done by looking at the equation given to us to find hints that will help solve it.
(x " first symbol " a) (x " second symbol" b) = 0
WIthout going too in depth:
the second symbol "+" tells us that the two symbols in our answer are the same
the first symbol "+" combined with the knowledge of second symbol "+" tells us that the two symbols in our answer are both "+"
next we know "a" times "b" = 4 and "a" + "b" = 4 so we find numbers that match this description e.g. 2 and 2 and so we have found our answer
x^2 + 4x + 4 = 0 = (x+2)(x+2)
and so x = -2
2) Using the quadratic formula:
(-b +- sqrt(b^2 - 4ac))/2
This method is simpler and requires you to only plug in the numbers in the correct place of the formula, the a, b and c from the formula come from the general equation: ax^2 + bx + c which all quadratic formulas can be related to.
e.g.) ax^2 + bx + c and so a = 1, b = 4 c = 4 in our example
and our result is -2see more
