Question

determine the type of number that the solution x^2+2x+5=0

Answer 1

b^2 - 4ac = 0, 1 real solution
b^2 - 4ac > 0, two real solutions
b^2 - 4ac < 0, two complex solutions

Answer 2

the type of number would be 1 real solution?

Answer 3

b^2 - 4ac,
a = 1, b = 2, c = 5
b^2 - 4ac =
2^2 - 4(1)(5) =
4 - 20 =
-16

Answer 4

so what type of number is it. this may be a ridiculous question but im very confused

Answer 5

Since you see that b^2 - 4ac is a negative number, that means the solutions to this equation are two complex (imaginary) numbers.

Answer 6

ok i get it now thanks:)
