Answer:
b is the answer
Step-by-step explanation:
Answer:
use the formula a^3+b^3= (a+b)-3ab(a+b)
in above question assume (a+b) as a and 1 as b
later in (a+b+1) take (a+b) as a and 1 as b
and use the formula (a+b)^2 = a^2+2ab+b^2
Answer:
Step-by-step explanation:

4(x - 1) = – 4 + 4x
4x-4 = -4+4x
so Any value of ( x ) makes the equation true.
All numbers are a solution
