Question

is a^2 + b^2 =0 linear ?

Answer 1

no it's not , because all the variables are raised to the power of 2
in the linear equation or function, the must be raised to the first power
like : y = mx+b

Answer 2

what does it mean "the must be raised to the first power" ? Do you mean that in linear eq the power of any variable should be 1 ?

Answer 3

yes

Answer 4

@y2o2 thanks bro

Answer 5

anytime ;)

Answer 6

Hard to be sure what this even is, since there is only one real solution, a=b=0.
