Use synthetic division here, if you know it.  Use -3 as divisor and use the coefficients 1  -2  -15  -14  -12.  If there is no remainder, then x+3 is a factor of the given polynomial.

      _____________________
-3  /  1   -2   -15   -14   -12
             -3     15      0    42
      ---------------------------------
         1   -5      0    -14    30

There's a non-zero remainder:  30.  This means that the polynomial has the value 30 when x = -3, and that (x+3) is NOT a factor of the poly.

How would you calculate 7x + 1=68 with only one variable? (Working please)
Tanya [424]
Well if you're solving for x this would be rather simple. 7x +1=68   , then you'd minus 1 from both sides. 7x = 67   then divide 67 by 7. The answer isn't a whole number so x would either be 67/7 or 9.57.. etc.
