given equation ,
x²-8x + 1280= 0
splitting the middle terms,
x² -40x+32+1280 =0
x(x-40) + 32(x-40) =0
x-40 = 0 or x+32 =0
x=40 and x=-32
wish it helps !! :)

now bye
Solution is not there until we go into complex numbers and that would be too complex to solve so probably question should have -1280 and then ur solution would be correct
Ok let it get deleted
On your demand i answered it but I do not know whether you know about i (iota) complex number
@ SharmaShivam - how did you confirm the Answer ?

Answer:
On Demand , i is iota a complex number and i²=-1
x = 4+35.55 i
x = 4 - 35.55 i
Please mark the answer as "The Brainliest answer" if you like it
Step-by-step explanation:
x²-8x+1280 = 0
x²-8x+16+1264=
x²-8x+16 = -1264
(x-4)² = √-1264
x-4 = +35.55 i , - 35.55 i ( i is iota and iota² = -1)
x = 4+35.55 i
x = 4 - 35.55 i
Mark the answer as brainliest if you liked
