Question

x2 – 5x + 4

Answer 1

[AI-generated answer — Bot]

This is a trinomial that can be factored into two binomials:

x2 – 5x + 4 = (x – 4)(x – 1)

To check this, you can use FOIL (first, outer, inner, last) method:

(x – 4)(x – 1) = x * x + x * (-1) + (-4) * x + (-4) * (-1) = x2 – x – 4x + 4 = x2 – 5x + 4

Therefore, the factored form of x2 – 5x + 4 is (x – 4)(x – 1).
