To solve the product of these two numbers we should know about expression and like terms.
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
like terms are those terms that are having the same variables, also the variables are of the same order as well.
for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
The product of (a-5) and (a+3) is a²-2a-15.
Given to us
[tex]\ \ \ (a-5) \times(a+3)[/tex]
Adding the like terms,
[tex]\= a^2 +3a -5a -15\\= a^2 -2a -15[/tex]
Thus, the product of (a-5) and (a+3) is a²-2a-15.
