Hello All... :) I have to give to give a 5 minute speech for an English Assessment.... Approximately how many words would you read at a medium pace? i.e. With pauses etc... Thanks... :D

I agree... :)

Thanks... :D The best way to solve them... :D Yes, the discriminant is like the key of life!

Because the number under the root is negative... We can't square a negative number... :) Thanks Herioc. Tried to +1 but couldn't!

Awe yeah, thanks for your hint... ;D

But the second one isn't in the answers... Should it be? :D

Uh ha... Good.. :) When I do the first one I get (1 +- √5)/2

And instead of just doing it in the calculator.... Simplify it so I get exact values??? :D

No, it's not possible to square root a negative number... Thanks heaps for reminding me of this! :D Sorry... Can you show me how to solve the first quadratic and I'll have a go at the second... :)

Hello All... :) Could someone please help me with the following questions? Solve.... Q1. x^4 - 7x^2 - 18 = 0 Here is my working... a= x^2 and a^2 = (x^2)^2 a^2 - 7a - 18 = 0 (a-9)(a+2) = 0 a = 9, -2 Now... why do we only use a = 9 to get the two results +3 and -3 ...

Thanks heaps Menomaths... No worries, thanks for taking the time. :)

Thanks heaps.. By this way I get n = -1... Now for the 2nd answer... :)

Oh sorry... Do you have time to do it? :) Thanks in advance. :)

No... n = -1 and 3 (Apparently). :D

Yup, I'd got that far... :) So 2@ + 1 = n (sum) .... OR .... 2@ + @ = n (product)

Hello All. :D Could someone please help me with this Q? Q. Find values of n in the equation 2x^2 - 5(n - 1)x + 12 = 0 if the two roots are consecutive. Thanks for your help in advance. :)

Cool as!! Anywhere else?

The flu?
