Answer:

-47

Explanation:

First you use PEMDAS, so you start with the exponent.

-5^2 = 25

Then you multiply the -2!!! Not the 2 with the 25, multiplying the 2 is a common mistake.

When you multiply the -2, it results in:

3 - 50

= -47

Answer:

-47

Explanation:

Original Equation:


f(-5)=3-2(-5)^2

Square the -5 (this cancels out the negative sign


f(-5)=3-2(25)

Multiply 2 and 25


f(-5) = 3-50

Subtract 50 from 3


f(-3) = -47

I'm a bit confused by what you mean factor the equation? Given the context. But I'm going to assume the equation is:
f(x)=3-2x^2. Which isn't exactly factorable.
