The discriminant is the bit under the radical, the .
Because it's under a radical, it's what tells you how many and what kind of solutions you have (two real, one real, or two imaginary/complex solutions).
Does that answer your question? Or do you need an example?
Suppose you had the equation , then you'd have:
, and
You'd plug those values into to see if the discriminant was positive, zero, or negative:
Since that is 37 (a postiive number), you'd have two real solutions.
Answer:
B
Step-by-step explanation:
sin(45)=x/3
sqrt(2)/2x==x/3
You can do 1/24; 3/24; 5/24 in that order
I solved for x i hope that’s what you needed
