Factor the expression [tex]10r - 15[/tex].

[tex]
\begin{aligned}
10r - 15 & = 5(2r - 3)
\end{aligned}
[/tex]

Answer :

Sure! To factor the expression [tex]\(10r - 15\)[/tex], we should look for the greatest common factor (GCF) of the two terms in the expression.

1. Identify the GCF:
- For the terms [tex]\(10r\)[/tex] and [tex]\(15\)[/tex], the GCF of 10 and 15 is 5.

2. Factor out the GCF:
- We divide each term in the expression by the GCF, which is 5.
- [tex]\(10r \div 5 = 2r\)[/tex]
- [tex]\(15 \div 5 = 3\)[/tex]

3. Write the factored expression:
- Once you factor out 5, the expression becomes [tex]\(5(2r - 3)\)[/tex].

So, the factored form of the expression [tex]\(10r - 15\)[/tex] is [tex]\(5(2r - 3)\)[/tex].
