The factor from the expression 5(3x² + 9x) - 14 is not listed among the options you provided. However, I can help you simplify the expression and identify the factors within it.
To simplify the expression, we can distribute the 5 to both terms inside the parentheses:
5(3x² + 9x) - 14 = 15x² + 45x - 14
From this simplified expression, we can identify the factors as follows:
15x²: This represents the term with the variable x squared.
45x: This represents the term with the variable x.
-14: This represents the constant term.
Therefore, the factors from the expression are 15x², 45x, and -14.
