## anonymous one year ago Need help 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.

1. MrNood

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

2. anonymous

yes

3. MrNood

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

4. anonymous

That the part i need help with

5. MrNood

you just said oyu know what it is you know a,b and c what is the formula for the discriminant??

6. MrNood

the formula is $b ^{2} - (4 \times a \times c)$ a=3 b=3 c=2 work out the value from the equation above

7. anonymous

-4ac+b^2

8. MrNood

that is the correct formula now work out the value using a=3 b=3 c=2

9. anonymous

rational

10. MrNood

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
