The question is asking for what the value of a is for the given polynomial.
They gave you a factor to that polynomial, (x+a), and told you that a can be any real number beside 0.
You might remember that when you factor an equation, all you're doing is finding for what value of x will give you an answer of 0.
This is what you're doing now but in reverse. You're given x+a as a factor, so you know that x=-a will make the function equal 0.
So plug x=-a into the function and solve for a. You'd find that you get a=0 and a=2; however, the question stated that a≠0, so the only answer left is a=2.
Answer:
The answer is
Step-by-step explanation:
Given:
Darcy harvest 8 3/4 acres of corn every 5/6 of an hour.
Now, to find the acres per hour it takes to harvest.
Darcy harvest =
The time he took to harvest =
So, to get the acres per hour we put formula:
Therefore, the answer is
we know that
Francine uses cup of pineapple juice for every
cup of orange juice to make a smoothie
so
by proportion
Find the number of cups of pineapple for one cup of orange juice
therefore
<u>the answer is</u>
When 6 is subtracted from the square of a number, the result is 5 times the number, then the negative solution is -1
<h3><u>Solution:</u></h3>Given that when 6 is subtracted from the square of a number, the result is 5 times the number
To find: negative solution
Let "a" be the unknown number
Let us analyse the given sentence
square of a number =
6 is subtracted from the square of a number =
5 times the number =
<em><u>So we can frame a equation as:</u></em>
6 is subtracted from the square of a number = 5 times the number
<em><u>Let us solve the above quadratic equation</u></em>
For a quadratic equation where
Here in this problem,
Substituting the values in above quadratic formula, we get
We have two solutions for "a"
We have asked negative solution. So a = -1
Thus the negative solution is -1
