\n" ); document.write( "i know what the quadratic formula is but i don't know how to apply it to this particular question
\n" ); document.write( "the question is: 2x^2+7x = 1-2x^2
\n" ); document.write( "the fact that it isn't in the form x^2 + bx + c = 0 is making it hard for me solve,
\n" ); document.write( "at the moment i've got as far as changing the equation to 2x^2+7x - 1-2x^2=0
\n" ); document.write( "but i don't know whether thats right or wrong :S

You can put this solution on YOUR website!
the question is: 2x^2 + 7x = 1 - 2x^2
\n" ); document.write( ":
\n" ); document.write( "Group like terms on the left
\n" ); document.write( "2x^2 + 2x^2 + 7x - 1 = 0
\n" ); document.write( ":
\n" ); document.write( "Combine the like terms
\n" ); document.write( "4x^2 + 7x - 1 = 0
\n" ); document.write( ":
\n" ); document.write( "Now it is in the familiar ax^2 + bx + c form that we all recognize and love.
\n" ); document.write( "where a = 4; b = 7; c = -1
\n" ); document.write( ":
\n" ); document.write( " $\"x+=+%28-7+%2B-+sqrt%287%5E2+-+4+%2A+4+%2A-1+%29%29%2F%282%2A4%29+\"$
