FORMATTING: Write your answer in the form [p(x), q(x), r(x)], including square brackets and commas between the terms. Use strict scientific calculator notation in your answer, in particular * for multiplication (e.g. 3x² is written 3*x^2, and 2(3x + 1) is written 2*(3*x+1)). Note that you should not have sqrt() in your answer. Answer: [p(x), g(x), r(x)] = 16

IX HA
Knowing that lim
= 0 for a > 0, we want to evaluate the following limit.
a) This is an indeterminate form of the type
O ∞0/∞0 0 0⁰ 00×∞ ○ 0/0
lim
XXX
O ∞-∞
O 1%
2+6x
b) Rationalize this expression to find polynomials p(x), q(x) and r(x) such that
√x² + 6x - √√x² - 7x
x²
AB
7x
p(x)
√√q(x) + √(x)
FORMATTING: Write your answer in the form [p(x), q(x), r(x)], including square brackets and commas between the terms. Use strict scientific calculator
notation in your answer, in particular * for multiplication (e.g. 3x² is written 3*x^2, and 2(3x + 1) is written 2*(3*x+1)). Note that you should not have
sqrt() in your answer.
Answer: [p(x), g(x), r(x)] =
= 1 and present your answer in the form
c) Simplify the expression from part (b) so that the numerator is a constant. Use the fact that
C
√s(x) + √(x) '
p(x)
√(x) + √r(x)
where C' is a constant and s(x) and t(x) don't diverge to ∞o as x increases.
