Find the product of -1 + 3i and its conjugate. The answer is a + bi where The real number a equals
The real number b equals

Step-by-step explanation:

Conjugate of -1 + 3i = -1 - 3i

Their Product:

Since the answer is 10, It seems like:

a + bi = 10

So, This means that:

a = 10

b = 0

answer: i believe it’s 245.04

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
