Answer:
Step-by-step explanation:
Let f(x) be the polynomial function of minimum degree with real coefficients whose zeros are 5, -3, and -1 + 3i be f(x).
By the complex conjugate property of polynomials, -1-3i is also a root of this polynomial.
Therefore the polynomial in factored form is
We expand to get:
We expand further to get:\
Answer:
About 71% of the books were mystery books
Step-by-step explanation:
To find the percentage of something you simply divide the amounts. 17 of the 24 books were mystery so to find the percentage of mystery books you do 17 divided by 24

12×2+6= your anwser. (tip:12×2 is 24)
Answer:
2c*(-4 + 3d)
Step-by-step explanation:
To factorize the equation 2c*2 -12c+6cd, put the common term 2c out and you would get:
2c*2 -12c+6cd
= 4c - 12c + 6cd
= -8c + 6cd
= 2c*(-4 + 3d)
This is the simpliest form you can get
