Answer:
(a) The discriminant is 49.
(b) There are 2 solutions and they are rational.
(c) The real solutions are x = 3 and x = -0.5
Step-by-step explanation:
(a) To find the discriminant you must plug a, b, and c into [tex]b^2-4ac[/tex]
so [tex]-5^2-4(-3)(2) = 49[/tex].
(b) The number of solutions can be found by graphing the equation. They are rational because they are either positive or negative numbers and can be represented by a quotient.
(c) The solutions can be found by factoring. I forget how to find irrational solutions sorry.
I hope this helps!
