Given the following constants for a standard form quadratic equation, determine the nature of its roots.
a=3, b=3,c=2

A.
rational
B.
irrational
C.
no real solutions
D.
There is not enough information provided.

Answer 1

do you know what the 'discriminant' of a quadratic equation is?

Answer 2

yes

Answer 3

so work out the value of the discriminant from the values of a,b and c as given

Answer 4

That the part i need help with

Answer 5

you just said oyu know what it is

you know a,b and c

what is the formula for the discriminant??

Answer 6

the formula is

\[b ^{2} - (4 \times a \times c)\]

a=3
b=3
c=2

work out the value from the equation above

Answer 7

-4ac+b^2

Answer 8

that is the correct formula

now work out the value using
a=3
b=3
c=2

Answer 9

rational

Answer 10

so - you have asked for help - and I have given you a number of guides to the answer.

If you ignore the guide then you will just guess the answer, as you have done.

Instead of guessing try this:

-4ac+b^2

now work out the value using
a=3
b=3
c=2
