Please help me! Given f(x)=4x^2+6x and g(x)=2x^2+13x+15, find (f/g)(x). Show your work.

First, I would factor f(x) and g(x).
f(x)=2x(2x+3)
g(x)=(2x+3)(x+5)
Then divide.
(f/g)(x)= $\frac{2x(2x+3)}{(2x+3)(x+5)}$
Cancel out (2x+3)
you are left with 2x/(x+5)

Javine says, "To multiply by 1000, I just add three zeros." Kian says, "I times by 10, then times by 10 and times by 10 again."

Answer:

Kian's method is correct.

Step-by-step explanation:

Javine says, "To multiply by 1000, I just add three zeros." He is incorrect.

Kian says, "I times by 10, then times by 10 and times by 10 again. When he multiply 1 by 10, it becomes 10. Then if he again multiply by 10, it becomes 10×10 = 100. And at last when he multiply again 10, it becomes 100×10 = 1000. It means Kian's methods for multiplying by 1000 is correct.
