Carl wants to find the product 30×5/6.Which of the following best explains how he can find the product mentally? A. He knows that 30÷5 is 6. He then multiplies 6 by 6 to get 36.
B. He knows that 30×6/6 is 30. He then subtracts 1 from 30 to get 29.
C. He knows that 3×6=18.He then adds 18 and 5 to get 23.
D. He knows that 30×1/6 is 5. He then multiplies 5 by 5 to get 25.

D

30×5/6 = 25

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.
