6. rohit singh

X= -3or -5 so answer is 2

7. ankit singh

4 real roots
Using Descartes theorem

8. SAHIL SINGHA

-3, -5, -7, -9

9. janardan singh

3 -'ve, 1+ve= total 4

10. Weeshal Singh

Sir , no values simultaneously satisfy both parts of the equation.Hence ,the answer is ''0''.

2 real roots

18. Madhav Kumar

2 roots

19. Abhishek Saurav

No real roots possible

20. Swati Suman

no real roots possible

21. Madhav Kumar

-12+root124/2 and-12-root124/2

22. RITESH KUMAR

Two real roots [-6+√(✓24)-3]. And[-6√(✓24)-3]

23. Darshan Singh

Awesome

24. Utkarsh Srivastava

-7,-3,-9,-5 are the roots since equation is of degree 4

25. ROHIT TRIVEDI

5+2√35, 5-2√35, 7+2√35, 7-2√35 are 4 roots

26. Adarsh Maurya

4 real roots (All are negative)

27. rishi roy

28. DAYANAND SHARMA

x=-3 ,-5, -7 ,-9

29. sumit panday

-5 ,-7

30. waseem akram

(x+5)^4+(x+7)^4=2^4+2^4
X+5=+/-2, x+7=+/-2
X=-2+-5=-7,x=2-5=-3,x=-2-7=-9,x=2-7=-5
X=-3,-5,-7,-9

31. Abhimanyu kumar

Expand and factorize to get:
(x²+12x+39)²=24

Now, solve to get

X²+12x+36=2rt6-3, x²+12x+39=-2rt6

Solve to get:
X=-6±rt(2rt6-3)

So total number of real roots are 2.

32. A

-3,-7,-5,-9

Super sir aap online course available hai kya

34. Meenakshi Shukla

35. niket shrivastava

2 real roots

36. Vikash Singh

It must be 2
On breaking 32 into two parts i.e 2^4+2^4
we get x=-3 and -5

37. NITISH KUMAR

SIR I WANT ENQUIRY OF OFF LINE CLASS

38. Rahul Kumar

NO REAL ROOT POSIBLE

39. Vaibhav Sharma

There are no real roots, hence answer is 0(zero)

40. Pankaj Kumar

There are 4 real roots one positive and three negetive roots by descarte's rule of signs…

41. shubhanshu sharma

real roots will be 2 first root is between -4 and -5 second root is between -7 and -8
root can be find by newton rapshon method
