Question

how do i evaluate this limit:
lim x tends to 5 x-3-2x^2/1+3x

Answer 1

Please use ( ) and superscripts as ^.

Otherwise, there is no hope of following the problem.

Answer 2

The denominator (1 + 3x) does not vanish when x=5. So, just evaluate the function at x = 5.

Answer 3

ok lemme write it over then:
How do i find the lim x-->5 (x-3-2x^2)/(1+3x)

Answer 4

so drwls do i have to change the top into something similar or just plug in x=5 into the entire equation.

Answer 5

sorry i mean the top looks like a quadratic do i break it down or just leave it as it is and just plug in x=5 into the entire equation?

Answer 6

oh don't worry drwls, i now understand. thanks!

Answer 7

you take the evaluated equation and you lose all similar sines by xsing. onse you are left with a group of different signs you square all them and then do the problem. once you have the answer you take the square root of that and then times it by 2^
drwls don't know what he is talking about
