The other 10 yard lines should be marked negative on the opposite side.
3x^3+12x^2+3x
The GCF would be 3x, you can factor out a 3x
3x(x^2+4x+3)
You can further factor the problem...
3x(x+3)(x+1)
Another equivalent form can be made if you simply distribute 3x into x+3
(3x^2+9x)(x+1)
Thats easy its x = 5 , 4 times 5 is 20 minus 2 equals 18
have a nice day
