2x^3-16x^2-40x=0 factor
ExtremeBDS [4]

The given expression is

2x^3-16x^2-40x=0

We extract the common factor 2x.

\begin{gathered} 2x(x^2-8x-20)=0 \\ 2x=0\rightarrow x=0 \\ x^2-8x-20=0 \end{gathered}

The first solution is 0.

Now, we solve the quadratic expression. We have to find two numbers whose product 20 and whose difference is 8. Those numbers are 10 and 2.

x^2-8x-20=(x-10)(x+2)<h2>Hence, the given expressions expressed, as factors, is</h2>2x^3-16x^2-40x=x(x-10)(x+2)

What is the value of x?
Aleksandr-060686 [28]

Answer:

70

Step-by-step explanation:

Since these two are same side interior angles, their measures must be supplementary. This means that they must add up to 180 degrees. Therefore:

45+2x-5=180

2x+40=180

2x=140

x=70

Hope this helps!
