Lesson 1: Multiplying monomials by polynomials

Multiply monomials by polynomials: Area model

We can use an area model to multiply a polynomial by a single term. Created by Sal Khan.

• At Sal says that 2x times 3x is equal to 6x^2. The reason why he put the ^2 is because he is solving for the area right? if thats true then how come 2x times 4 isnt equal to 8x^2? Please let me know if im wrong
• Think about it: 2x * 3x can be rewritten as 2 * 3 * x * x.

This becomes 6x^2. 2x * 4 can be rewritten as 2 * 4 * x. This becomes 8x. Hope this helps!
• yo yall trying to play some 2k21 rq
• dis leson makky myy bwain hurty
• So true op
• the area in the first example is -9.16666666666+3.9965I
it's a negative number !?
• Where did you get that number? Also, the rules of polynomial is that the exponents should not be negative.

• I cannot figure it out. What is the sum of 6x2+8x? what is than the outcome? thank in advance
• You'll see a lot in algebra that often times you won't see any sum. This is one of such scenarios
• What is the difference between a trinomial and a polynomial?
• A trinomial is a term used specifically for a polynomial with 3 terms. The difference is that a Trinomial is a specific kind of Polynomial, while a Polynomial is the general description of 'nomials' with a definite number of terms
• At , are we basically adding up all of the areas? Like what exactly is going on T_T
