1. Guide to Multiplying a Binomial and a Trinomial (5x^2+2x^2+1)(3x+4)

2. (5x^6+2x^2+1)(3x+4) 1 2x^2 5x^6 3x 4 Step 1: first you have to draw a box three by three then put each number in the

3. (5x^6+2x^2+1)(3x+4) 2x^2 1 5x^ 6 3x^2 4 The next step is to multiply each number then add the exponents.

4. Step 3: then you had to put these numbers in order by greatest to least. Then combine the like terms. 15x^8+20^6+6x^4+8x^2+3x^2+4

5. And this is what I got after I combined my like terms. And this Is also my answer. 15x^8+20x^+11^4+3x+4
