Question 594671
Find the remaining zeros of of f(x) given that c is a zero. Then re-write f(x) in a completely factored form. f(x)=2x^3+15x^2+22x-15; c=1/2 is a zero.
**
dividing by synthetic division:

...1/2...|.....2......15......22.......-15.............
...........................1........8.........15......
.................2......16......30.........0....
f(x)=(2x-1)(2x^2+16x+30)
f(x)=(2x-1)(2x+10)(x+3)
