จงหาเซตคำตอบของสมการ x3 - 10x2 + 27

จงหาเซตคำตอบของสมการ x3 - 10x2 + 27x -18 = 0

วิธีทำ

ให้ f(x) = x3 - 10x2 + 27x -18

∴ f(1) = 1 - 10 + 27 -18 = 0

∴ x - 1 เป็นตัวประกอบของ f(x)

∴ x3 - 10x2 + 27x -18 = (x-1)(x2 - 9x + 18)

= (x-1)(x-3)(x-6)

x3 - 10x2 + 27x -18 = 0

(x - 1) (x - 3) (x - 6) = 0

x = 1, 3, 6

∴เซตคำตอบของสมการนี้คือ {1, 3, 6}

What sets the answer to the equation x3 - 10x2 + 27x -18 = 0 How to F (x) = X3 - 10x2 + 27X -18 ∴ F (1) = 1 - 10 + 27 -18 = 0 ∴ x -. 1 is a factor of F (x) ∴ X3 - 10x2 + 27X -18 = (x-1) (X2 - 9x + 18) = (x-1) (x-3) (x-6) X3 - 10x2 + 27X. -18 = 0 (x - 1) (x - 3) (x - 6) = 0 x = 1, 3, 6 ∴ set answer to this equation is {1, 3, 6}.

find the solution of the equation set X3 - 10x2 27x - 18 = 0

how do

to f (x) = X3 - 10x2 27x - 18

∴ f (1) = 1 - 10 27 - 18 = 0

∴. X - 1 as of F (x)

∴ X3 - 10x2 27x - 18 = (x-1) (X2 - 9x 18)

= (x-1) (x-3) (X-6)

X3 - 10x2 27x - 18 = 0

(x - 1). (x - 3) (x - 6) = 0

x =,, 1 3 6

∴ set solution of the equation is 1 3 6} {,,,
