To solve this problem, we'll follow these steps:
Let's begin the simplification process:
First, we identify and group the like terms in the expression .
Notice: - The terms involving are and . - The terms involving are and . - The terms involving are , and the multiplication term with is .
Step 2: Combine the like terms:
The term can be rearranged with as .
Thus, after combining the terms, we have:
.
Therefore, the simplified form of the expression is:
Are the expressions the same or not?
\( 20x \)
\( 2\times10x \)
bc means 'b times c' while 3c means '3 times c'. These are different because one has variable b in it! You can only factor: bc + 3c = c(b + 3).
Like terms must have identical variable parts. For example: 5a and 9a are like terms, but 5a and 5b are not. The coefficients can be different, but the variables must match exactly.
The term bc is not the same as c! You cannot write bc + 3c = 4c. Instead, factor out c: bc + 3c = (b + 3)c, which gives the correct form.
Yes! Addition is commutative, so you can write the terms in any order you prefer. Many people like to put them in alphabetical order: 10a + 11b + (b + 3)c.
Substitute simple values like a=1, b=1, c=1 into both the original expression and your simplified version. If they give the same result, you're correct!
