Step 1: write the number as a product, helps visualizing common factors.
3*(5g)*g^2 + (2*3)*3 g^2-2*(5g) -2*(2*3)
I've marked things being repeating, so, group them up
5g(3g^2-2)+6(3g^2-2)
Now you have a common factor again
(3g^2-2)(5g+6)
Extra, if you want to split the first one, you can see it as the difference of (\sqrt{3}g)^2 and \sqrt{2} which is further split into( \sqrt{3} g+\sqrt{2}) (\sqrt{3} g-\sqrt{2})

Determine if the following table represents a quadratic function.
snow_tiger [21]

Answer:

<em>The options are not visible enough (See Explanation)</em>

Step-by-step explanation:

Given

x:-  1   || 2   || 3   || 4   || 5

y:-  13 || 22 || 37 || 58 || 85

Required

Determine if the function is quadratic

Calculate the difference between the values of y

Difference = 22 - 13 = 9

Difference = 37 - 22 = 15

Difference = 58 - 37 = 21

Difference = 85 - 58 = 27

<em>The resulting difference are: 9 || 15 || 21 ||  27</em>

Next; Calculate the difference between the difference of values of y

Difference = 15 - 9 = 6

Difference = 21 - 15 = 6

Difference = 27 - 21 = 6

<em>The resulting difference are: 6 || 6 || 6</em>

<em>For the function to be quadratic, the above difference must be the same and since they are the same (6), then the function represents a quadratic function.</em>
