Factoreach expression. 8x 3 + 28x 2 + 40x

Mathematics
1 answer:
Sindrei [870]3 years ago
5 0

Hello :)

First, find the common factor of all of the terms.

<h2>8x^3</h2>

4 ⋅ 2 = 8

x ⋅ x ⋅ x = x^{3}

<h2>28x^2</h2>

4 ⋅ 7 = 28

x ⋅ x= x^{2}

<h2>40x</h2>

4 ⋅ 10 = 40

x = x

the common factor of all of the terms is 4x.

Next, divide the original equation by 4x.

4x(8x^{3} +28x^{2}+40x)

\frac{8x^{2} }{4x}+\frac{28x^2}{4x}+\frac{40x}{4x}

4x(2x^2+7x+10)

Using the distributive property what is 2(-5+3) as an equivalent expression
photoshop1234 [79]

Answer:

-4

Step-by-step explanation:

Because when distrubuting first you distribute 2(-5) which gives you -10 and then you distribute 2 into 3 which is 2(3) which gives you 6. So now you have -10+6. So you can further simplify that into -4. We get -4 because -10 + 6 is -4. And the 4 is negitive because there are more negitives than positives.

Can someone explain?

The correct statement regarding the quadratic function is:

K. I, II and III.

<h3>What is a quadratic function?</h3>

A quadratic function is given according to the following rule:

y = ax^2 + bx + c

If a > 0, it has a maximum value, and if a < 0, it has a minimum value.

The extreme value is (x_v,y_v), in which:

  • x_v = -\frac{b}{2a}
  • y_v = -\frac{\Delta}{4a}
  • \Delta = b^2 - 4ac

The solutions are:

  • x_1 = \frac{-b + \sqrt{\Delta}}{2a}
  • x_2 = \frac{-b - \sqrt{\Delta}}{2a}

In this problem, we have a function h(t). Changing the coefficient c, the h-intercept h(0) changes. Looking at the formulas in the bullet point, the value of \Delta changes, meaning that both the maximum value y_v and the t-intercepts t_1 and t_2 will change, so option K is correct.
