Used ChatGPT 4o with Mathematics GPT
I think kuch part rheh gaya hai what's the condition for both roots wala
array, ruk puchta hu Sir se
itna he hai bas
Agar dono root hai toh 2 baar sign change hoga matlab really sign change hua nhi
Yes
Toh how can we say it's none roots vs 2 roots
What is the ans?
@¹¹⁷sos
No roots
I think we did a similar kind of question but it was but diff, let me search for it
Ok yah diff, give me some time I’ll try
Yes
Diff bw B and C
Also yah that ans is coming , let me send rq
Wait u want a hint or the solution ?
Solution
I’ll send pic if needed but
Sol:
Find f of 1 and f of 2 which is 5a + 3b + 2c
And from the question a and 4a + 3b + 2c have the same sign so their sum will always be positive or negative
a+ 4a+ 3b+ 2c
= 5a + 3b + 2c
Which is nothing but f of 1 and f of 2
So obv they aren’t the roots as it should be equal to zero and not less/more than zero
@¹¹⁷sos
Ye toh hai but how can we say that uske beech me kitne root hai
Ohh yes I get ur question, let me try
@SirLancelotDuLac ek baar dekhna
