Question

I need help please,
Let f(x) = x – 3 and g(x) = x + 11. Find f(x) • g(x).

x2 – 8x – 33

x2 – 8x + 14

x2 + 8x + 14

x2 + 8x – 33

Answer 1

Just multiply
(x-3)(x+11)
You will have
x² - 3x + 11x - 33 = x² + 8x - 33

Answer 2

do you do alike terms?

Answer 3

I really need help anyone.

Answer 4

just straightforward multiplication, element by element

Answer 5

\[f(x)=x-3\]\[g(x)=x+11\]\[f(x) \cdot g(x) = (x-3)(x+11)\]\[\color{green}x(x+11) -\color{purple}3(x+11)\]\[x(x)+11(x) -3(x)-3(11)\]Can you simplify this now?

Answer 6
