The number of bags of soybean seeds n that a farmer needs varies jointly as the number of acres a to the planted and the pounds of seed needed per acre p, and n 980 when a 700 cares and p 70 lb/acres. find n when a 1000 acres and p 75 lb/acres.

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.

it is true
