I dont understand how to do integers so if you could explain with you answer that would be amazing and thank you.

1.2×10‐2

Integer is a number which is not a fraction and is whole number. Yes whole numbers are 0,1,2 and so on but integer can also be negative such as -1,-2 etc.

-3⁰= -1 which is integer

18/3(is a fraction but when solved)=6 which is integer

root under49 is 7 which is integer.

some numbers which are not integer

1.2,-3.6,1/2 etc.

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.
