Question

Find all real solutions of the equation. (Enter your answers as a comma-separated list. If there is no real solution, enter NO REAL SOLUTION.)
x5 − 625x = 0

Answer 1

(0,5)

Answer 2

That is x=0 or x=5

Answer 3

what about this one :
Find all real solutions of the equation. (Enter your answers as a comma-separated list. If there is no real solution, enter NO REAL SOLUTION.)
x3 − x2 + 5x − 9 = x2 + 1

Answer 4

bring everything over to one side, group in pairs.

Answer 5

x^3 -2x^2 +5x -10 =0

x^2 ( x-2) +5(x-2) =0

(x^2 +5)(x-2) =0

Answer 6

so the only answer is 2

Answer 7

?

Answer 8

yes
