the answer is 0

can you guess what could be the reason behind zero ?

no.. something about (0, -1000)

@eliassaab sir, help

haha

hello
because P(x) is a strictly increasing function since\[P'(x)=57x^{56}+77x^{10}+3>0\]

@lovekblue why are you laughing bro lol

there you go @lovekblue

but P(x) starts from (0,-1000), wouldnt it cross 0 in some time?

no, it would not it will tend to zero but won't cross zero

how do u know o_o

check out the definition that muku has mentioned above

but what he talks about is P'(x)

P'(x) is strictly increasing.. that doesnt help saying it wont cross 0...

ohh right
