Answer:

(x - 1) (x + 3) (x + 5)

Step-by-step explanation:

The constant at the end (-15) can only be factored into 1, 3 and 5, assuming integers. Then, you only have to choose which one of these gets the minus sign.

I'm not sure if this approach will work in general, but it works for this one.

Solve the equation for the letter L: A=LW

jarptica [38.1K]

$\frac{L}{A} =LW$ ⇒ Multiply both sides by A
$\frac{LA}{A}=LWA$ ⇒ The terms 'A' on the LHS cancel each other
$L=LWA$ ⇒ Divide both sides by 'L'
$\frac{L}{L}= \frac{LWA}{L}$ ⇒ The terms 'L' on the LHS cancel each other to '1' and the terms 'L' on the RHS will also cancel each other
$1= WA$

The correct answer is the last option = none of the above
