\"x%5E2\"- 3x + 2 = 0
\n" ); document.write( "1)Solve by factoring.
\n" ); document.write( "First fiqure out the factors of 2; 2,1
\n" ); document.write( "now added together they give us 3, so we have;
\n" ); document.write( "(x-2)(x-1)\r
\n" ); document.write( "\n" ); document.write( "2)Solve by completing the square.
\n" ); document.write( "We start by moving 2 to the right side;
\n" ); document.write( "\"x%5E2\"-3x=-2
\n" ); document.write( "The coefficient of x=-3; we divide -3 by 2 and square the result;
\n" ); document.write( "(\"-3%2F2\")^2=\"9%2F4\"
\n" ); document.write( "Add \"9%2F4\" to both sides;
\n" ); document.write( "\"x%5E2\"-3x+\"9%2F4\"=-2+\"9%2F4\"
\n" ); document.write( "simplified;
\n" ); document.write( "\"%28x-3%2F2%29%5E2\"=\"1%2F4\"
\n" ); document.write( "square root both sides;
\n" ); document.write( "x-\"3%2F2\"=(+/-)\"sqrt%281%2F4%29%29\"
\n" ); document.write( "(\"sqrt%281%2F4%29\" = 1/2)
\n" ); document.write( "Add \"3%2F2\" to both sides;
\n" ); document.write( "x=\"3%2F2\"(+/-)\"1%2F2\"
\n" ); document.write( "x=\"3%2F2\"+\"1%2F2\" or x=\"3%2F2\"-\"1%2F2\"
\n" ); document.write( "x=2 or x=1\r
\n" ); document.write( "\n" ); document.write( "3)Solve by using the quadratic formula.
\n" ); document.write( "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( "a=1; b=-3; c=2
\n" ); document.write( "\"x=%28-%28-3%29%2B-+sqrt%28%28-3%29%5E2-4%281%29%282%29%29%29%2F2%281%29\"
\n" ); document.write( "\"x=%283%2B-sqrt%289-8%29%29%2F2\"
\n" ); document.write( "\"x=%283%2B-sqrt%281%29%29%2F2\"
\n" ); document.write( "x=\"%283%2B-1%29%2F2\"
\n" ); document.write( "x=\"%283%2B1%29%2F2\" or x=\"%283-1%29%2F2\"
\n" ); document.write( "x=2 or x=1
