Answer:
Step-by-step explanation:
equations are created to solve for a certain variable. you can use the data given in the word problem to formulate a valid equation that incorporates all important components of the word problem. the variable can be represented as any letter (most commonly x or y) to find a value that is inconsistent or unknown. this is helpful to find a certain thing in the problem, such as the amount of hours needed to earn a certain amount of money.

on top,bottom and four on every sides.
Answer:
![\frac{a-3}{(a-2)(a-6)}](https://tex.z-dn.net/?f=%5Cfrac%7Ba-3%7D%7B%28a-2%29%28a-6%29%7D)
Step-by-step explanation:
has the common multiple of a. If you factor it out, you get
.
also has a common multiple of a. Once factored, you get
. This equation can be further factored to get
.
Put these two expressions over one another and you get
.
Are you sure you have typed it in correctly?
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 5
B = 1
C = 3
B2 - 4AC =
1 - 60 =
-59
Applying the quadratic formula :
-1 ± √ -59
x = ——————
10
But we can't square root a negative number. When you square a number, whether it's a negative, or a positive, you'll always get a positive integer. That's why you can't square root a negative. Please check if you've copied out the question right, so we can help you accordingly.
