Solve the equation 14z=224

Step-by-step explanation:

To solve for in this equation, we need to isolate by itself on one side of the equation.

To do this, we need to get rid of the that is being multiplied by the on the left-hand side of the equation. This can be done by dividing both sides by :

Therefore, the solution to the equation is .

Step-by-step explanation:

14z = 224

divide both sides by 14

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.
