What are the steps for using a compass and straightedge to construct an equilateral triangle? drag the steps and drop them in order from start to finish. construct a point at one of the two intersection points of circle e and circle f and label this point g .construct eg¯¯¯¯¯ and fg¯¯¯¯¯ . construct ef¯¯¯¯¯ .construct a circle with point e as the center and a circle with point f as the center with each circle having radius ef .

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.
