\[\frac{ 6x ^{2}- 5x - 3 }{ x ^{2}-2x +6 } \le 4\]
OpenStudy (anonymous):
Then the least ans the highest values of 4x^2 are
OpenStudy (anonymous):
and*
OpenStudy (primeralph):
Let's see you try,

\[\frac{ 2x ^{2} + 3x - 27 }{ x ^{2} - 2x + 6 }\]
OpenStudy (paki):
if you make factors, will it work...
OpenStudy (anonymous):
all that is less than or equal to 0
OpenStudy (anonymous):
We have to use quadratic formula simple factorisation won't work here
OpenStudy (paki):
yup... then what will be the result...

the answer is 0 and 81 i don't know how they got it
OpenStudy (anonymous):
Or probably i have made some mistake in calculating
OpenStudy (anonymous):
no i haven't i checked it
OpenStudy (paki):

i posted it . It is exact
OpenStudy (paki):
ok
OpenStudy (dumbcow):
\[6x^2 -5x-3 \le 4(x^2 -2x+6)\]
\[2x^2 +3x-27 \le 0\]
\[(2x+9)(x-3) \le 0\]
\[-\frac{9}{2} \le x \le 3\]
OpenStudy (anonymous):
thats just the numerator right
OpenStudy (anonymous):
so about the denominator

OpenStudy (anonymous):
we can't factorise
OpenStudy (dumbcow):
no you get rid of fraction by multiplying the denominator over to right side
OpenStudy (anonymous):
it
OpenStudy (anonymous):
We don't know if the denominator is positive or not if it was positive infact we could have done it
