Hi there, firstly you have a quadratic equation and must find 2 numbers that add to give 8 and 14 however this does not have any two values and you must use the quadratic formula: $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$ \r
\n" ); document.write( "\n" ); document.write( "the values a,b,c are given by the general quadratic equation ax^2 + bx + c, in-which the corresponding values are the co-efficients (numbers in front of the x)\r
\n" ); document.write( "\n" ); document.write( "therefore a = 1, b = 8, c = 14\r
\n" ); document.write( "\n" ); document.write( "now put these values into the quadratic formula and solve.. at the final steps you should get two values such that: $\"x+=+%28-8+%2B+sqrt%28+8%5E2-4%2A1%2A14+%29%29%2F%282%2A1%29+\"$ and $\"x+=+%28-8+-+sqrt%28+8%5E2-4%2A8%2A14+%29%29%2F%282%2A1%29+\"$ \n" ); document.write( "
