About me

I am Gabriella and I am a 3rd year law student at Durham University. I love learning and would like to share this passion with you. I believe it important for everyone to achieve their best. Although I am studying law I took maths and science A levels. I can tutor 11+, maths, biology and chemistry to GSCE, and LNAT as well as support in writing personal statements.

How my sessions work

My sessions would be driven by what you need, and how you best learn. I can use different ways to explain theories and problems. I take a relaxed approach and it is important to me to understand how you best learn so I can prepare for your session appropriately. I would prepare for the topic(s) you would want to cover. Maths, biology and chemistry are a great subjects and I would love to share my enjoyment of it with you.

I can help you if you are preparing for your 11+ so that you gain confidence before you take the tests.

I can talk through the LNAT. I can also give you guidance on writing your personal statement.

About me

I am studying law alongside Manderin at Durham University. I enjoy the challenges of applying law to different situations. I have previously supported students at my former school(s) – helping primary school students with their reading, GSCE students with maths and chemistry, and running a learning session for A level biology students.

I look forward to hearing from you.

Simplify (3x^2 - 15x)/(3x^2 - 13x -10)

Begin by considering the numerator and denominator separately, simplify both: 1) 3x^2 - 15x Here, a common factor of 3x can be removed to give 3x(x^2 -5). 2) 3x^2 - 13x -10 This involves using two brackets each arranged as (ax+b)(cx+d). Unlike in 1), 3x cannot be removed as a common factor, ...

Begin by considering the numerator and denominator separately, simplify both:

1) 3x^2 - 15x

Here, a common factor of 3x can be removed to give 3x(x^2 -5).

2) 3x^2 - 13x -10

This involves using two brackets each arranged as (ax+b)(cx+d). Unlike in 1), 3x cannot be removed as a common factor, but 3x must exist in order for 3x^2 to be present, therefore you get (3x+b)(x+d). The next thing to consider is how to multiply b and d to obtain 10, the factors of 10 are 1, 10, 2 and 5. As "-10" is in the expression to be simplified, one of the signs must be a minus. So considering 2 and 5, there are two possible answers: (3x - 2)(x+5) or (3x+2)(x-5), multiplying these out you find that the latter is the only possible solution.

Finally, putting the new simplified fraction together you get: (3x(x-5))/((3x+2)(x-5), (x-5) cancel on the numerator and denominator giving you a final, simplified, fraction of 3x/(3x+2).
