What is limit of f(x) = (x^3-2x^2-9x+4)/(x^2-2x-8) as x approaches 4
sattari [20]
\displaystyle\lim_{x\to4}\frac{x^3-2x^2-9x+4}{x^2-2x-8}

First notice that x^2-2x-8=(x-4)(x+2). If x-4 is not a factor of the numerator, then there is a non-removable discontinuity at x=4, and a removable discontinuity otherwise.

You have 4^3-2\times4^2-9\times4+4=0, which means, by the polynomial remainder theorem, that x-4 is indeed a linear factor of the numerator. Dividing yields a quotient of

\dfrac{x^3-2x^2-9x+4}{x-4}=x^2+2x-1

so the limit is

\displaystyle\lim_{x\to4}\frac{x^2+2x-1}{x+2}=\frac{4^2+2\times4-1}{4+2}=\frac{23}6

When 5 is subtracted from the square of a number, the result is 4 times the number. Find the negative solution.
wariber [46]

Answer:

-1

Step-by-step explanation:

You can write it as...

x^{2} -5=4x

Carry the 4x

x^{2} -4x-5=0

Then use the quadratic formula to solve, since you want to find the negative solution, you don't need to find the positive solution, so we will have

(4-\sqrt{16+20}) /2=\frac{4-6}{2}=\frac{-2}{2} =-1

Therefore our answer is -1
