4x^4 - 6x^2 - 7 = 0 How can I factor it?

Answer:

You cannot solve by factoring

Step-by-step explanation:

We want to solve 4x^4-6x^2-7=0 by factoring.

We can rewrite as: 4(x^2)^2-6x^2-7=0

So we have a quadratic equation in x^2.

We split the middle term to get:

We look for  factors -28 that sum up to -6

This is not possible hence the given equation is not factorable

Naomi’s fish Is 40 mm long her guinea pig is 25 cm long how much longer is her guinea pig than her fish
tia_tia [17]
1.) Convert the measurements of Naomi's pets so that the two has the same unit of measurements. I will use cm.
                     1 mm = .01 cm;
Therefore:  40 mm = 4 cm is the length of the fish
2.) Subtract the pets' measurements:
         25 cm - 4 cm = 21 cm
3.) Therefore, Naomi's guinea pig is 21 cm longer than her fish.

Given the functions f(x) = x3 + x2 – 3x + 4 and g(x) = 2x – 4, what type of functions are f(x) and g(x)? Justify your answer. Wh
8090 [49]

The first function is a type of cubic function and second function is a type of linear function. The key feature(s) do f(x) and g(x) have in common as they both have value of domain and range as (-∞, ∞).

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The function given in the problem is:

f(x) = x³ + x² – 3x + 4

The highest degree (power) of this function is 3. Thus, this function is a type of cubic function.

The second function given in the problem is:

g(x) = 2x – 4

The highest degree (power) of this function is 1. Thus, this function is a type of linear function.

Both the function has the value of domain and range from -∞ to ∞ (-∞,∞).

Thus, the first function is a type of cubic function and second function is a type of linear function. The key feature(s) do f(x) and g(x) have in common as they both have value of domain and range as (-∞, ∞).

How would you solve 7c + 12 = -4c + 78
Svetach [21]
Hello!

7c+12 =-4c+78&#10; \\ 11c=66 \\ &#10;c=6

First we will get the variable in the correct side.
add 4c to 7c.
Second thing you will do is subtract 12 from 78

Now, divide 66 by 11 and you'll be left with c=6
