Question

I need help is it A B C or D

Answer 1

You need to factor this out. When you do this, though ugly, there are two solutions.

Answer 2

We evaluate b^2 - 4ac. If the answer is positive, then there are two real solutions. If it is zero, there is one real solution. If it is negative, there are 2 complex solutions. In this equation, a = 1, b = 5, c = 7. Now we plug in the numbers.


`5^(2)-4*1*7=1`

Because this answer is positive, there are two real solutions.
