You can put this solution on YOUR website!
It is very important to put parentheses and brackets around quantities because otherwise the questions have no meaning.\r
\n" ); document.write( "\n" ); document.write( "I understood your set up this way:\r
\n" ); document.write( "\n" ); document.write( "(5 + Q)/40 = 845/(Q + 5) + (Q/80)\r
\n" ); document.write( "\n" ); document.write( "Is this the fractional equation that you are trying to solve for Q?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "===================================================================\r
\n" ); document.write( "\n" ); document.write( "I received your e-mail. I will set it up and let you finish the problem.\r
\n" ); document.write( "\n" ); document.write( "We want to remove the fraction from both sides of the equation.\r
\n" ); document.write( "\n" ); document.write( "To do this, multiply both sides by the LCD.\r
\n" ); document.write( "\n" ); document.write( "After multiplication, this is what we have:\r
\n" ); document.write( "\n" ); document.write( "2(Q + 5)(Q + 5) = 67600 + Q(Q + 5)\r
\n" ); document.write( "\n" ); document.write( "We continue to break it down like this:\r
\n" ); document.write( "\n" ); document.write( "2(Q^2 + 10Q + 25) = 67600 + Q^2 + 5Q\r
\n" ); document.write( "\n" ); document.write( "2Q^2 + 20Q + 50 = 67600 + Q^2 + 5Q\r
\n" ); document.write( "\n" ); document.write( "Bring everything on the right side to the left but do not forget to change the sign of the terms you are moving to the left side.\r
\n" ); document.write( "\n" ); document.write( "2Q^2 + 20Q + 50 - Q^2 - 5Q - 67600 = 0\r
\n" ); document.write( "\n" ); document.write( "Q^2 + 15Q - 67550 = 0...This is a quadratic equation.\r
\n" ); document.write( "\n" ); document.write( "I'll let you take over from here on. To solve for Q, it is best to use the quadratic formula.\r
\n" ); document.write( "\n" ); document.write( "Understood?\r
