Question

What is the factorization of x^2-4x+3?

Answer 1

D. (x - 3)(x - 1)

Explanation:

Factor the following:

`\longrightarrow` x² - 4x + 3

The factors of 3 that sum to -4 are -1 and -3.

So,

`\longrightarrow` x² - x - 3x + 3

`\longrightarrow` x(x - 1) - 3(x - 1)

`\longrightarrow` (x - 3)(x - 1)
