From 7x%5E2%2B6x%2B2 we can see that a=7, b=6, and c=2


D=b%5E2-4ac Start with the discriminant formula.


D=%286%29%5E2-4%287%29%282%29 Plug in a=7, b=6, and c=2


D=36-4%287%29%282%29 Square 6 to get 36


D=36-56 Multiply 4%287%29%282%29 to get %2828%29%282%29=56


D=-20 Subtract 56 from 36 to get -20


So the discriminant is D=-20


Since the discriminant is less than zero, this means that there are two complex solutions.


In other words, there are no real solutions.
