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

Mathematics

ExtremeBDS [4]1 year ago

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)

A line with a slope of 3 passes through (2,5). Which choice is an equation of this line? Please help
jek_recluse [69]

Answer:

Top right.

Step-by-step explanation:

So we want a line with a slope of 3 and passes through (2,5).

To do so, we can use the point-slope form.

The point-slope form is:

y-y_1=m(x-x_1)

m is the slope and x₁ and y₁ is an ordered pair.

Thus, let m be 3, y₁ be 5, and x₁ be 2. Thus:

y-5=3(x-2)

Our answer is the top right :)
