If a polynomial with real coefficient has a complex zero, the conjugate of that number will be a zero as well.
So, if 4-6i is a zero, 4+6i will be a zero as well
If -2+11i is a zero, -2-11i will be a zero as well
So, the zeroes are

Answer:
The point estimate for the proportion of women with BRCA1 mutation is 0.168
Step-by-step explanation:
The point estimate for the proportion of women with BRCA1 mutation is the number of women with this mutation divided by the size of the sample.
Of the 173, they found that 29 had BRCA1 mutations.
29/173 = 0.168
The point estimate for the proportion of women with BRCA1 mutation is 0.168
