Answer 2

To find the expression P(x+3) + P(x-5) when P(x) = 4x - 3, we first need to substitute the given expression for P(x) into the given equation.

Step 1: Find P(x+3) Replace x in P(x) with (x+3): P(x+3) = 4(x+3) - 3 P(x+3) = 4x + 12 - 3 P(x+3) = 4x + 9

Step 2: Find P(x-5) Replace x in P(x) with (x-5): P(x-5) = 4(x-5) - 3 P(x-5) = 4x - 20 - 3 P(x-5) = 4x - 23

Now, we can find P(x+3) + P(x-5) by adding the expressions we obtained in Step 1 and Step 2:

P(x+3) + P(x-5) = (4x + 9) + (4x - 23)

Now, combine like terms:

P(x+3) + P(x-5) = 4x + 4x + 9 - 23

P(x+3) + P(x-5) = 8x - 14

So, the final expression for P(x+3) + P(x-5) is 8x - 14.
