question
express as a trinomial.
$(x + 3)(3x + 10)$

Explanation:

Step1: Apply FOIL method

$(x+3)(3x+10) = x\cdot3x + x\cdot10 + 3\cdot3x + 3\cdot10$

Step2: Calculate each term

$= 3x^2 + 10x + 9x + 30$

Step3: Combine like terms

$= 3x^2 + (10x+9x) + 30 = 3x^2 + 19x + 30$

Answer:

$3x^2 + 19x + 30$
