Answer:
A is the answer.
Step-by-step explanation:
We have
Factor the radical by taking perfect squares of the real numbers and the exponents.
56 can be made up of perfect 8, x^7 can be made up of x^6 and y^5 can be made up of y^3. So we get
Take the cube root of 8x^6y^3.
Which is 2x^2y.
A is the answer.
Answer:
Step-by-step explanation:
<u>Given information</u>:
- Polynomial function with real coefficients.
- Zeros: 0, 2i and (3+i).
For any complex number , the complex conjugate of the number is defined as .
If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.
Therefore, if f(x) is a polynomial with real coefficients, and 2i is a root of f(x)=0, then its complex conjugate -2i is also a root of f(x)=0.
Similarly, if (3+i) is a root of f(x)=0, then its complex conjugate (3-i) is also a root of f(x)=0.
Therefore, the polynomial in factored form is:
As we have not been given a leading coefficient, assume a = 1:
Expand the polynomial:
To write a fraction in simplest form, first we need to find the Greatest Common Factor (or GCF) of the numerator and the denominator.
The GCF of 26 and 39 is 13.
Therefore, we should divide both the numerator and the denominator by this number.
26 / 13 = 2
39 / 13 = 3
Therefore, 2/3 is 26/39 in simplest form.
