+-x%5E2-3x%2B4=0+
Use quadratic equation
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
+a+=+-1+
+b+=+-3+
+c+=+4+
x+=+%28-%28-3%29+%2B-+sqrt%28+%28-3%29%5E2-4%2A%28-1%29%2A4+%29%29%2F%282%2A%28-1%29%29+
x+=+%28+3+%2B-+sqrt%28+9+%2B+16+%29%29%2F%28-2%29%29+
x+=+%28+3+%2B-+sqrt%28+25+%29%29%2F%28-2%29%29+
x+=+%28+3+-+5%29%2F%28-2%29+
+x+=+1+
and
x+=+%28+3+%2B+5%29%2F%28-2%29+
x+=+-4+
