Question

5. If p(x) = x3 – x2 + x + 1, then value of (1)+ (−1) is​

Answer 1

Answer:

its wrong

Step-by-step explanation:

X+Y+Z=6

X²+Y²+Z²=14

X³+Y³+Z³=36

WE HAVE (X+Y+Z)³=X³+Y³+Z³+3(X+Y)(Y+Z)(X+Z)

6³=36+(3X+3Y)(XY+ZY+ZX+Z²)

216-36=3(X²Y+XYZ+ZX²+XZ²+Y²X+ZY²+XYZ+YZ²)

180/3=2XYZ+X²Y+ZX²+XZ²+Y²Z+ZY²+YZ²)
