Use the zero product property to find the equation x^2 + x - 30 = 12

x=6, add thirty to both sides 6 squared is 36, plus six is 42

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

true? is that what you're asking or do you mean something else?
