Question

find the zeros of this function. state the multiplicity of multiple zeros

y=(x=2)^2(x-5)^4

Answer 1

I'm assuming that the second = is actually a +

0 = (x+2)^2; x = -2, multiplicity of 2
0 = (x-5)^4; x = 5, multiplicity of 4

The multiplicity is the recurrence of that zero, in this case, the exponent.
The zero is the value of x for which y would equal 0.
