question
express as a trinomial.
(3x - 1)(x - 3)

Explanation:

Step1: Apply FOIL method

First terms: $3x \times x = 3x^2$
Outer terms: $3x \times (-3) = -9x$
Inner terms: $-1 \times x = -x$
Last terms: $-1 \times (-3) = 3$

Step2: Combine all terms

$3x^2 - 9x - x + 3$

Step3: Combine like terms

$3x^2 + (-9x - x) + 3 = 3x^2 - 10x + 3$

Answer:

$3x^2 - 10x + 3$
