If [tex]f(x) = x^2 - 5x[/tex] and [tex]g(x) = 2x - 3[/tex], which expression represents the product of these two functions?

1) [tex]x^2 - 3x - 3[/tex]
2) [tex]2x^3 - 13x^2 + 15x[/tex]
3) [tex]9x^2 - 15x[/tex]
4) [tex]2x^3 - 15x[/tex]

Answer (3)

p ro d u c t = f ( x ) ⋅ g ( x ) = ( x 2 − 5 x ) ( 2 x − 3 ) = 2 x 3 − 3 x 2 − 10 x 2 + 15 x = = 2 x 3 − 13 x 2 + 15 x ⇒ A n s . 2 )

2). (x² - 5x) (2x - 3) = 2x³ -13x² + 15x

The product of the functions f ( x ) = x 2 − 5 x and g ( x ) = 2 x − 3 is 2 x 3 − 13 x 2 + 15 x . Therefore, the answer is option 2.
