(4x2 + 8)(4x2 – 8)
16(x2 + 2)(x2 – 2)
16x4 + 16x – 16x – 64
Your answer should be 0.3000
Answer:
A. (x*2.5)*x
B. (32*2.5)*32=2560
Step-by-step explanation:
Step-by-step explanation:
f(x)=x^2+x
so
f(x-1) = (x - 1) ^ 2 + (x - 1)
= x^2 - 2x + 1 + x - 1
= x^2 - 3x
and
f(x+1) = (x + 1) ^ 2 + (x + 1)
= x^2 + 2x + 1 + x + 1
= x^2 + 3x + 2
now
f(x-1) + f(x+1) = 6
x^2 - 3x + x^2 + 3x + 2 = 6
2x^2 = 4
X = √2
brainliest pls took long enough to solve
