Solve the second equation to find the coordinate of point B. Show your work step by step. (2 points) 2.5= -2B+6

1.75

Step-by-step explanation:

-2b+6 = 2.5

-2b = 2.5-6

-2b = -3.5

b = -3.5 \ -2

b = 1.75

1.75

Step-by-step explanation:

-2b+6 = 2.5

-2b = 2.5-6

-2b = -3.5

b = -3.5 \ -2

b = 1.75

Step-by-step explanation:

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.
