\"3x+-+2+%28+x+%2B+3+%29+=+0\"
\n" ); document.write( "Firstly, expand the \"2%28x%2B3%29\" using the distributive law, this makes our equation \"+3x+-+2x+%2B+6+=+0+\"
\n" ); document.write( "Since you didn't provide a method, I will do it the easiest way, the quadratic formula.
\n" ); document.write( "\"+3x+-+2x+=+1x+=+x\"
\n" ); document.write( "\"+x+%2B+6+=+0\"
\n" ); document.write( "From here you can say that x = -6 straight away, but using the QUADRATIC FORMULA:
\n" ); document.write( "The standard formula that applies to the quadratic formula is \"ax%5E2+%2B+bx+%2B+c+=+0+\"
\n" ); document.write( "a = Coefficient of \"x%5E2\" b = Coefficient of \"x\" c = the single number value\r
\n" ); document.write( "\n" ); document.write( "a = 0 (\"1x%5E2+=+0\") b = 1 (\"x+=+1x\") c = 6
\n" ); document.write( "Quadratic Formula = \"x+=+%28-b+%2B-+sqrt%28+b%5E2-%284%2Aa%2Ac%29+%29%29%2F%282%2Aa%29+\"\r
\n" ); document.write( "\n" ); document.write( "WE CANNOT DO THIS! AS 2*a = 0 , which means we CANNOT divide by zero.
\n" ); document.write( "I will assume that your equation is \"%283x+-+2%29+%28+x+%2B+3+%29\"
\n" ); document.write( "Which is expanded to \"3x%5E2+%2B+7x+-+6+=+0\" which is fine for a quadratic equation.\r
\n" ); document.write( "\n" ); document.write( "a = 3 b = 7 c = -6
\n" ); document.write( "Now we substitute the a, b, and c values that are in your equation into this quadratic formula so it can return 2, (maybe 1 in this case) values of x.\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%28-7+%2B-+sqrt%28+7%5E2-%284%2A3%2A-6%29%29%29%2F%282%2A3%29+\"
\n" ); document.write( "\"x+=+%28-7+%2B-+sqrt%2849+-+-72%29%29+%2F+6\"
\n" ); document.write( "\"x+=+%28-7+%2B-+sqrt%2849+%2B+72%29%29+%2F+6\"
\n" ); document.write( "\"x+=+%28-7+%2B-+sqrt%28121%29%29+%2F+6\"
\n" ); document.write( "\"x=+%28-7+%2B-+11%29+%2F+6\"
\n" ); document.write( "THEREFORE
\n" ); document.write( "\"x+=+%28-7+%2B+11%29+%2F+6\"
\n" ); document.write( "\"x++=+4%2F+6\"
\n" ); document.write( "\"x+=+0.67%7D%7D%0D%0Aor+%0D%0A%7B%7B%7Bx+=+%28-7+-+11%29+%2F+6\"
\n" ); document.write( "\"x+=+-18%2F+6\"
\n" ); document.write( "\"x+=+-3%7D%7D%0D%0A%0D%0A%7B%7B%7Bx+=+0.67+or+-3\"
\n" ); document.write( "I personally think you mistyped the equation, it was \"%283x+-+2%29%28+x+%2B+3+%29+=+0\"
\n" ); document.write( "not \"3x+-+2+%28+x+%2B+3+%29+=+0\".
\n" ); document.write( "Thanks, remember to mark this as your solution if I got it!
