Answer: 
Step-by-step explanation:
You need to remember the mulplication of signs:

Knowing this, you can distributive the negative sign. Then you get:

Now you need to add the like terms. Then:

Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:

Answer:
No. It would be (x + 5)
Step-by-step explanation:
set each of the factors as equal to 0. So if you do x+5=0 then solve for x by subtracting 5 from both sides you get x = -5
The clue is to switch the sign from the factor to get the value of the variable and vice-versa.
Definition
Functions have zeros or x-values that generate function values equal to zero.
Equations have roots or solutions that can be substituted into the polynomial in order to generate a value equal to zero.
Given:
![f(x)\text{ = -}\frac{1}{3}\sqrt[]{x}\text{ + 3}](https://tex.z-dn.net/?f=f%28x%29%5Ctext%7B%20%3D%20-%7D%5Cfrac%7B1%7D%7B3%7D%5Csqrt%5B%5D%7Bx%7D%5Ctext%7B%20%2B%203%7D)
To convert this to an equation, we set f(x) equal to zero i.e

The resulting equation is:
Answer:
Step-by-step explanation:
sub equation 1 into 2
2-5x=x²-2x-8
0=x²-2x+5x-8-2
0=x²+3x-10
0=(x-2)(x+5)
x=2 or x=-5
sub x into equation 1
y=2-5(2) or y=2-5(-5)
y=-8 y=27
Answer:
Answer: First option is correct.
A
Step-by-step explanation:
Since we have given that
First step is to collect the like terms together :
The equation can become 6x + 1 = 1 by combining like terms.
On the other hand we didn't apply distributive property.
Hence, First option is correct.
