Answer:

Yes

Answer: x = 0

Explanation:

Yes it is.

Down is the answer how to solve this equation and the steps.

Step 1 :

Equation at the end of step 1 :

qx - (((4 • (x2)) - 3x3) + 8x) = 0

Step 2 :

Equation at the end of step 2 :

qx - ((22x2 - 3x3) + 8x) = 0

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

qx + 3x3 - 4x2 - 8x =

x • (q + 3x2 - 4x - 8)

Equation at the end of step 4 :

x • (q + 3x2 - 4x - 8) = 0

Step 5 :

Theory - Roots of a product :

5.1 A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation :

5.2 Solve : x = 0

Solution is x = 0

Solving a Single Variable Equation :

5.3 Solve q+3x2-4x-8 = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Answer: x = 0

Hope this helps.
