Question

Help Math 60points please

Answer 1

ANSWER:

On solving equation by quadratic formula method, we get

D = b² – 4ac

• (–5)² – 4 × 1 × 3
• 25 – 12
• 13

D > 0, so it has real roots.

Now, x = – b ± √D/2a

• – 5 ± √13/2

So, Correct choice - [A] & [C].

Answer 2

Answer:

solving equation by quadratic formula method, we get:

D = b² - 4ac

=(-5)² - 4 × 1 × 3

=25-12=13

D> 0,

so it has real roots.

x=- b ± √D/2a

- 5 ± √13/2

Correct choice [A] and [C].
