-distribute or distribution or distributive property
-like terms
-binomial
-trinomial
-simplify

(3x^2-2)(2x^2+5x+7)
Step 1: (3x^2*2x^2)+(3x^2*5x)+(3x^2*7)-(2*2x^2)-(2*5x)-(2*7)
Step 2: (6x^4)+(15x^3)+(21x^2)-(4x^2)-(10x)-(14)
Step 3-answer:6x^4+15x^3+17x^2-10x-14

Answer 1

Here, I'll have a try:
This expression is the multiplication of a binomial and a trinomial.. The binomial has two terms, while the trinomial has three terms. Use the distributive property of multiplication, 
Step 1, multiply every term of the trinomial with the first term of the binomial, then multiple every term of the trinomial with the second term of the binomial. Use parenthesis to separate each multiplication to avoid confusion.
step 3, simply every multiplication 
step 4, add up like trms
