Understand the problem

It is possible to use the distributive property to simplify the expression

(a+b)(cg) (a+b)(c\cdot g)

Step-by-step solution

To solve this problem, we must determine if we can apply the distributive property to simplify the expression (a+b)(cg) (a+b)(c \cdot g) .

The distributive property states that for any three terms, the expression x(y+z) x(y+z) results in xy+xz xy + xz . Here, we have the sum (a+b) (a + b) and the product (cg) (c \cdot g) .

We can treat (cg) (c \cdot g) as a single term because it involves multiplication, which makes it like a single number or variable in terms of manipulating the expression algebraically. Therefore, using the distributive property, we distribute (cg) (c \cdot g) over the terms within the parentheses:

  • Step 1: Distribute cg c \cdot g to a a , yielding acg acg .
  • Step 2: Distribute cg c \cdot g to b b , yielding bcg bcg .

Hence, the simplified expression is:

acg+bcg acg + bcg .

Therefore, the correct answer, according to the choices provided, is:

No, acg+bcg acg + bcg .

Final Answer

No, acg+bcg acg+\text{bcg}

Key Points to Remember

Essential concepts to master this topic
  • Rule: Treat products like cg c \cdot g as single terms when distributing
  • Technique: Distribute (cg) (c \cdot g) to each term: a(cg)+b(cg) a(c \cdot g) + b(c \cdot g)
  • Check: Final form acg+bcg acg + bcg has same variables multiplied together ✓

Common Mistakes

Avoid these frequent errors
  • Distributing to individual variables instead of the entire product
    Don't distribute (a+b) (a+b) to just c c and g g separately = ac+ag+bc+bg ac + ag + bc + bg ! This ignores that cg c \cdot g is already multiplied together as one unit. Always treat products like (cg) (c \cdot g) as single terms when applying distributive property.

FAQ

Everything you need to know about this question

Why can't I distribute to c and g separately?

+

Because cg c \cdot g is already multiplied together as one unit! It's like having the number 6 - you wouldn't break it into 2×3 when distributing. Treat (cg) (c \cdot g) as a single factor.

How is this different from (a+b)(c+g)?

+

Great question! In (a+b)(c+g) (a+b)(c+g) , you have addition inside both parentheses, so you distribute each term to each term. But (cg) (c \cdot g) is multiplication, making it one combined factor.

What does 'acg + bcg' actually mean?

+

It means a×c×g a \times c \times g plus b×c×g b \times c \times g . All three variables in each term are multiplied together. You can also factor this as cg(a+b) cg(a + b) to check your work!

Can I simplify acg + bcg further?

+

Yes! You can factor out the common factors cg cg to get cg(a+b) cg(a + b) , which takes you back to the original expression. This confirms your distribution was correct.

Why does the question say 'No' for the correct answer?

+

The question asks if we can use distributive property to simplify the expression. Since acg+bcg acg + bcg is actually more complex than (a+b)(cg) (a+b)(c \cdot g) , we haven't truly simplified it - just expanded it!
