Answer 9

f(x)=(x+1)^2+(x-1)^2=x^2+2x+1+x^2-2x+1=2x^2+2

Answer 10

but wait !

Answer 11

formula for expansion
(a+b)^2=a^2+2ab+b^2
(a-b)^2=a^2-2ab+b^2

Answer 12

i think u will be able to solve it by these formulas

Answer 13

\[f(x)=(x+1)^2+(x-1)^2\]
\[f(x)=x^2+2x+1+x^2-2x+1\]
\[f(x)=2x^2+2\] tada
