Answer 2

Given:

An algebraic expression x² - 4x + 3.

To Find:

The value of the expression at x = 3 is?

Solution:

The given problem can be solved using direct substitution.

1. The given expression is x² - 4x + 3.

2. The value of the expression at x = 3 is calculated as,

=> f(x) = x² - 4x + 3,

=> f(3) = x² - 4x + 3,

=> (3)² - 4(3) + 3,

=> 9 - 12 + 3,

=> 12 - 12 = 0.

3. The value of the expression at x = 3 is 0.

Therefore, the value of the expression at x² - 4x + 3 at x = 3 is 0.
