Question

use the discriminant to determine the type and number of solutions.
-3x^2+2x+4=0
A) 2 rational solutions
B) 2 imaginary solutions
C) 1 rational solution
D) 2 irrational solutions

Answer 1

The discriminant is \[\large b^2-4ac\]

Answer 2

\[\large b = 2 \ , \ a = -3 \ , \ c = 4 \]

Answer 3

If it's positive/perfect square it has 2 real solutions
If it's 0 it has one repeating solution
If it's negative it has no real solutions/2imaginary solutions

Answer 4

\[\large b^2-4ac = (2)^2-4(-3)(4) = ?\]

Answer 6

Ty :)

Answer 7

i get b^2-4ac=52

Answer 8

Good

Answer 9

so its C?

Answer 10

Nope. it's a positive outcome, hence what @Luigi0210 stated.
