An experiment was conducted to determine whether a deficiency of carbon dioxide in the soil affects the phenotype of peas. listed below are the phenotype codes where 1 equals smooth dash yellow, 2 equals smooth dash green, 3 equals wrinkled dash yellow, and 4 equals wrinkled dash green. do the results make sense? 2 1 2 4 1 1 4 4 2 4 4 2 3 4

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.
