Expand the LHS and then move the RHS to the LHS and simplify.
There is still more to do.
OpenStudy (robtobey2):
Expand means to multiply out.
OpenStudy (thomasfire55):
?
OpenStudy (princeharryyy):
are you given options?
OpenStudy (thomasfire55):
no

The following is from the Mathematica program and the terms are not in classroom order.
\[6 x^2+x-(x+292)-2=0 \]\[6 x^2-294=0\]The above can be simplified and factored.
OpenStudy (princeharryyy):
than you have to multiply the LHS and solve for the value of x.
jhonyy9 (jhonyy9):
(2x-1)(3x-2) =x+292
6x^2 -4x-3x +2 =x+292
6x^2 -8x -290 =0
3x^2 -4x -145 =0 so just solve this quadratic for x
OpenStudy (radar):
@jhonyy9 You did not copy the problem as given, you changed the sign.
OpenStudy (robtobey2):
\[6 x^2-294=0 \]\[x^2-49=0 \]

yes right there is a sign inversed what i changed - sorry
OpenStudy (radar):
yes, robtobey has resolved it down to the difference of two perfect squares, where it is easy to solve by factoring.
