# How did u find the AQA p3 exam? watch

1. i thought it was alright... I think i should get a C for it...only need around 50% for an A so im happy
i think i messed up in question 6 and the vectors question...everythin was alright
2. was gud i thought also, need about 72% for an A so fingers crossed.
3. can someone please tell me what u get when u integrate (5 - x^2)/(25-x^2)
4. ∫ (5-x²)/(25-x²) dx = ∫ (25-x² - 20)/(25-x²) dx
= ∫ (25-x²)/(25-x²) dx - 20 ∫ 1/(25-x²) dx
= ∫ 1 dx + 20 ∫ 1/(x²-25) dx
= x + 2 ln|(x-5)/(x+5)| + C

The second integral can be done by partial fractions if you split the denominator to (x-5)(x+5).
