Brayden and his cousin Kayla live twenty miles away from each other. On the same day, Brayden recorded 1.046 inches of rain at his house and Kayla recorded 1.062 inches of rain at her house. Whose house received fewer inches of rain that day?

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.
