Afew years ago, a total of 2669 thousand people lived in the metropolitan areas of las vegas, nevada, and sacramento, california. sacramento had 275 thousand more residents than las vegas. what was the population of each metropolitan area?

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.

(23*2)-12=x     x=34
