Question

express as a trinomial.
(3x - 4)(3x - 6)
answer

Explanation:

Step1: Apply FOIL method

First terms: $3x \cdot 3x = 9x^2$
Outer terms: $3x \cdot (-6) = -18x$
Inner terms: $-4 \cdot 3x = -12x$
Last terms: $-4 \cdot (-6) = 24$

Step2: Combine like terms

$9x^2 + (-18x - 12x) + 24 = 9x^2 - 30x + 24$

Answer:

$9x^2 - 30x + 24$
