Answer:

yes

Step-by-step explanation:

First and foremost this is because all quadratic equations always have 2 possible solutions because its degree is 2. and the degree determines how many solutions it has. The next reason is because when you find the discriminant and nature of roots this will also prove as a reason why he is correct because d=b²-4ac and

d=(10)²-4 (4) (-8)

=100+128

=228

and 228 is more than 0 therefore it has 2 real solutions
