Hich of the following describes the best method of solving two-step equations? A.
Apply the multiplication property of equality first, and then apply the addition property of equality to isolate the variable.
B.
Apply the addition property of equality first, and then apply the multiplication property of equality to isolate the variable.
C.
Apply only the multiplication property of equality to isolate the variable.
D.
Apply only the addition property of equality to isolate the variable.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

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.

a

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
