You can put this solution on YOUR website!
3(x^2-3) = 35x + 19
\n" ); document.write( "put the equation in the standard form: ax^2 + bx^2 + c = 0
\n" ); document.write( "3x^2 - 9 - 35x - 19 = 0
\n" ); document.write( "3x^2 - 35x - 28 = 0
\n" ); document.write( ":
\n" ); document.write( "the quadratic formula
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( ":
\n" ); document.write( "a=3, b = -35; c = -28
\n" ); document.write( "\"x+=+%28-%28-35%29+%2B-+sqrt%28-35%5E2-4%2A3%2A-28+%29%29%2F%282%2A3%29+\"
