GIVEN:
We are given the following polynomial;
Required;
We are required to factorize this polynomial completely.
Step-by-step explanation;
To factorize this polynomial, we start by grouping;
We now take the common factor in each group;
Next, we factorize the first parenthesis. To do this we set the equation equal to zero and solve for x as follows;
Therefore, the factors of the other parenthesis are;
Therefore, the complete factorization of the polynomial is;
ANSWER:
Option C is the correct answer.
9m-28=2m
9m-28-2m=2m-2m
(9m-2m)-28=0
7m-28=0
7m-28+28=0+28
7m=28
(7m)/7 = 28/7
m=4
<span><span>If you would like to solve the equation </span>- 7 * x
- 3 * x + 2 = 8 * x - 8, you can calculate this using the following steps:<span>
- 7 * x - 3 * x
+ 2 = 8 * x - 8
- 7 * x -
3 * x - 8 * x = - 8 - 2
- 18 * x =
- 10 /(-18)
x = 10 / 18
x = 5/9
<span>The
correct result would be </span>5/9<span>.</span></span></span>
You may notice that all of the terms have a common factor: 
. So, let's take the out of all the terms. This gives us:
Using the Zero Product Property, we can say that both 
and 
.
Let's solve both. is obvious, but we still need to solve our other term:
- Apply the Zero Product Property
Our answer is x = -6, 0, 4.
Answer:
5 seconds
Step-by-step explanation:
When the ball returns to its original height, it will be 96 ft from the ground. That means we want to solve for t ...
h(t) = 96
96 +80t -16t^2 = 96
16t(5 -t) = 0 . . . . subtract 96 and factor
This equation is true for t=0 and for t=5.
After 5 seconds, the ball will pass the top of the building on the way down.
