Question 1000953
Solve what?  Two rectangle dimensions given as expressions, and no question to answer. What is the question?


"Area is 294 square meters";

{{{(2x-1)(x+3)=294}}}
{{{2x^2-x+6x-3-294=0}}}
{{{2x^2+5x-297=0}}}-----------maybe factorable.  Not sure until try or attempt discriminant.


(discriminant is  {{{25+4*2*297=2401=49^2}}});
Factorable, most likely but easiest to use general formula for a quadratic equation.


{{{x=(-5+- sqrt(49^2))/(4)}}}


{{{x=(-5+- 49)/4}}}
You want the PLUS form because a negative x could make less sense.
{{{x=44/4=11}}}
{{{highlight(x=11)}}}-----------What now, are the length and width!!!!
