You can put this solution on YOUR website!
Jolene,\r
\n" ); document.write( "\n" ); document.write( "here goes...but please look at the previous answer i have given. I have done so many quadratics. Just take some time to read a couple...i do try to explain what i am doing, so you should then try it yourself and that way, by trying (and getting some wrong) you will learn it better :-)\r
\n" ); document.write( "\n" ); document.write( "I assume you want to have it solved? so, this means, what values of x when y=0...\r
\n" ); document.write( "\n" ); document.write( "\"x%5E2+-+6x+%2B+2+=+0\"\r
\n" ); document.write( "\n" ); document.write( "This does not factorise easily, so i will use te quadratic formula,\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28b%5E2+-+4ac%29%29%2F%282a%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%28-%28-6%29+%2B-+sqrt%28%28-6%29%5E2+-+4%281%29%282%29%29%29%2F%282%2A1%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%286+%2B-+sqrt%2836+-+8%29%29%2F%282%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%286+%2B-+sqrt%2828%29%29%2F%282%29\"\r
\n" ); document.write( "\n" ); document.write( "Now you can either get your calculator out now and work out this to however many decimal places required or you can do the following...\r
\n" ); document.write( "\n" ); document.write( "now, as 28 can be written as 7x4, i shall write:\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%286+%2B-+sqrt%287%29%284%29%29%2F%282%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%286+%2B-+sqrt%287%29sqrt%284%29%29%2F%282%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%286+%2B-+2sqrt%287%29%29%2F%282%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%286+%2B+2sqrt%287%29%29%2F%282%29\" or \"x+=+%286+-+2sqrt%287%29%29%2F2\"\r
\n" ); document.write( "\n" ); document.write( "so,
\n" ); document.write( "\"x+=+3+%2B+sqrt%287%29\" or \"x+=+3+-+sqrt%287%29\"\r
\n" ); document.write( "\n" ); document.write( "these 2 answers are much neater than what your calculator gives you AND are the precise answers, not something rounded up by you.\r
\n" ); document.write( "\n" ); document.write( "Hope you followed this.\r
\n" ); document.write( "\n" ); document.write( "Try your own now :-D\r
