Which of the following is a polynomial with roots 3, 5i, and −5i?

jek_recluse [69]

$x_{1}=3 \\ \\ x_{2}=5i \\ \\ x_{2}=-5i \\ \\ f(x)=(x-x_{1})(x-x_{2})(x-x_{3})=(x-3)(x-5i)(x+5i)= \\ \\ =(x-3)(x^{2}+25)=x^{3}+25x-3x^{2}-75=x^{3}-3x^{2}+25x-75$

Which of the following equations is equivalent to 2/3x - 1/2y = 6?

Nostrana [21]

Answer:

4x - 3y = 36

Step-by-step explanation:

2/3x - 1/2y = 6

Multiply each side by 6 to get rid of the fractions

6* (2/3x - 1/2y) = 6*6

Distribute the 6

12/3 x - 6/2y = 36

4x -3y = 36
