Answer:
p(x) + p(-x) = 6 is
Step-by-step explanation:
In this question, we are tasked with calculating what p(x) + p(-x) will be
From the question, we know that p(x) = x + 3
Then p(-x) will be p(-x) = -x + 3
Thus p(x) + p(-x) = x + 3 -x + 3
p(x) + p(-x) = 3 + 3 = 6
Answer:
7x4+2x3-4x2-5
Step-by-step explanation:
We will start solving this question by opening the bracket first
So let's solve
(7x4+2x3-3)-(4x2-9x+2)
7x4+2x3-3-4x2+9x-2
Collect like terms
7x4+2x3-4x2-3-2
7x4+2x3-4x2-5
So the final answer is 7x4+2x3-4x2-5
