Solving the Absolute Value Quadratic: |x² - 6x + 8| = 0

Question

x26x+8=0 |x^2-6x+8|=0

Video Solution

Step-by-Step Solution

To solve the equation x26x+8=0 |x^2 - 6x + 8| = 0 , recognize that the absolute value of a number is zero if and only if the number itself is zero. Therefore, we set the expression inside the absolute value to zero:

x26x+8=0x^2 - 6x + 8 = 0

Next, we attempt to factor the quadratic expression:

The expression x26x+8x^2 - 6x + 8 can be factored into:

(x2)(x4)=0(x - 2)(x - 4) = 0

Now, apply the zero product property, which states if a product equals zero, at least one of the factors must be zero. So, set each factor equal to zero:

  • x2=0x - 2 = 0 gives x=2x = 2
  • x4=0x - 4 = 0 gives x=4x = 4

Thus, the solutions to the equation x26x+8=0 |x^2 - 6x + 8| = 0 are:

x=2 x = 2 and x=4 x = 4 .

Answer

x=2 x=2 , x=4 x=4
