Edit - apologies for misreading. Numbers adjusted below.
You have p probability of winning 1.44 net profit and (1-p) probability of losing 2, since probabilities must add to 1. Breaking even means an average profit of 0, so set the equation to 0 and solve for p.
1.44p - 2(1-p) = 0
3.44p = 2
p = 58.14%
If you want to brush up on your algebra (which you should, since it will help with poker), Khan Academy and PatrickJMT are good resources.
