To solve the expression [tex]\( a^2 - 5b \)[/tex], follow these steps:
1. Identify Variables: Recognize that [tex]\( a \)[/tex] and [tex]\( b \)[/tex] are variables.
2. Understand the Expression: The given expression is in the form of:
[tex]\[
a^2 - 5b
\][/tex]
Here, [tex]\( a \)[/tex] is squared, which means [tex]\( a \)[/tex] is multiplied by itself (i.e., [tex]\( a \times a \)[/tex]). The term [tex]\( 5b \)[/tex] means that [tex]\( b \)[/tex] is multiplied by 5.
3. Simplify the Expression: The expression [tex]\( a^2 \)[/tex] remains as it is, indicating the square of [tex]\( a \)[/tex]. The term [tex]\( -5b \)[/tex] indicates that [tex]\( 5b \)[/tex] is subtracted from [tex]\( a^2 \)[/tex].
4. Result: The simplified form of the expression is:
[tex]\[
a^2 - 5b
\][/tex]
So, the simplified form of the given expression is [tex]\( a^2 - 5b \)[/tex]. This conclusion is drawn based on understanding the individual components and their operations in the expression.
