Best ResponseYou've already chosen the best response.1Yes, the equation is only ever equal to 0 when either x is 7 or x is 7. Thus: Zeros: x = 7, 7 Multiplicities are just the number of times each zero occurs. That is to say, the power or exponent of the zero. In this case, we (x+7)^2 and (x7)^2, each occurs twice. Therefore, the multiplicity of the zero x = 7, is 2 (since it's power is 2), and the multiplicity of the zero x = 7 is also 2 (since it's power is also 2).
