Answer:

x=3

Step-by-step explanation:

f(x) = x^3 -3x^2 +2

g(x) = x^2 -6x +11

Set them equal to each other

x^3 -3x^2 +2 = x^2 -6x +11

Subtract x^2 from each side

x^3 -3x^2 +2 = x^2 -6x +11

x^3 -3x^2-x^2 +2 = x^2-x^2 -6x +11

x^3 -4x^2 +2 =  -6x +11

Add 6x to each side

x^3 -4x^2+6x +2 =  -6x+6x +11

x^3 -4x^2+6x +2 =  11

Subtract 11

x^3 -4x^2+6x +2-11 =  11-11

x^3 -4x^2+6x -9 =  0

Factor

(x-3)(x^2-x+3)=0

Using the zero product property

x-3 =0   x^2 -x+3 =0

x=3       x^2 -x+3 =0

             This will give a complex solution

Answer:

x = 3

Step-by-step explanation:

given:

f(x) = g(x)

f(x) = x³ - 3x² + 2

g(x) = x² - 6x + 11

find: the value of x

solution:

  • as given f(x) = g(x)
  • equate each side x³ - 3x² + 2 =  x² - 6x + 11
  • combine similar terms and equate to zero: x³ - 4x² + 6x - 9 = 0
  • solve by factoring: (x - 3) (x² - x + 3)
  • use the Zero factor principle: x - 3 = 0
  • x = 3
  • for x² - x + 3 = 0 ----this is a complex solution.

therefore, the value of x = 3
