Question

Need help with this equation. Just need to make sure I have the answer correct. 3xsquared-4x=2xsqaured +2 using the quadratic formula.

Answer 1

what values did u take for a,b,c ?

Answer 2

a=1, b=-4, c= -2

Answer 3

thats correct :)
what did u get ?

Answer 4

4 plus or minus square root of 24 divided by 2 (but that can also be reduced)

Answer 5

yes, tried reducing ?

Answer 6

2+ square root of 24, and 2 mius square root of 24

Answer 7

nopes.
\(\huge \sqrt{24}=\sqrt{4(6)}=2\sqrt6\)
so
\(\huge\frac{4\pm 2\sqrt{6}}{2}=??\)

Answer 8

Ok. I know how to break down square roots, so I have to do that each time. And now, would the answer be 2 plus or minus 2 square roots of 6?

Answer 9

no!
\(\huge\frac{4\pm 2\sqrt{6}}{2}=\frac{4}{2}\pm \frac{2\sqrt6}{2}=?\)

Answer 10

Got ya. The divisor should apply to both the whole number and square root which means that this is now 2 plus or minus 1 on the square root of 6.

Answer 11

yes, u have to separate denominator.example:
\(\huge\frac{10+20}{10}\ne 1+20\)
\(\huge\frac{10+20}{10}= \frac{10}{10}+\frac{20}{10}\)

Answer 12

final answer here \(\huge 2\pm\sqrt6\)
