B or d can be
Z=0. P=0
Expression yr)^2-(xq)^2
Y=-x√2. Q=-r
(xq)^2
Option b

x^(2a)=y^(2b)=z^(2c)

x^(2a)=z^(2c)
z=x^(a/c)

y^(2b)=x^(2a)
y=x^(a/b)

x^2=yz
x^2=x^(a/b)•x^(a/c)

a/b+a/c=2

(ab+bc+ca)/bc=a/c+1+a/b=2+1=3

D✅

Explain anyone

x^2-2x=7
(x+2)^2-6(x+2)=7+4-12
x+2+1/(x+2)=6

(x+2)^4+1/(x+2)^4=(6^2-2)^2-2=1154

Constant term -2a^2
-2*81=-162 only perfect square
Options A
Otherwise write those terms which can make 4 degree
3ax^4+3x^4+10x^4-2ax^4
X^4(3a+13-2a)
A+13=4
a=-9
-2(81)=-162
