A light year is the distance that light travels in one year (One light-year equals 5,878,625,370,000 miles (9.5 trillion km)). Determine the number of miles, meters, and kilometers in one light year.

answer: there are 453.592 grams in a pound.

step-by-step explanation:

where is the questions

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.
