Question

√z2+8z+4=z solve

Answer 1

Could you put in ^ for exponents to make it clearer? I'm not sure of what the first term is supposed to be.

Answer 2

√z^2+8z+4=z

Answer 3

Do you mean \[\sqrt{z^2 + 8z + 4} = z?\]

Answer 4

If so, square both sides and acquire \[z^2 + 8z + 4 = z^2\] and you'll be able to solve it quickly from there.
