Answer :
Answer:So, the trinomial expression for the product (x + 3)(3x + 10) is 3x2+19x+303x2+19x+30.
Step-by-step explanation:
First, distribute x to both terms in the second parenthesis:
x×3x=3x2x×3x=3x2
x×10=10xx×10=10xNext, distribute 3 to both terms in the second parenthesis:
3×3x=9x3×3x=9x
3×10=303×10=30Now, combine like terms:
3x2+10x+9x+303x2+10x+9x+303x2+(10x+9x)+303x2+(10x+9x)+303x2+19x+30
