Answer:
-b/2a
Step-by-step explanation:
We presume you want to find values of x that make this true.
Subtract the right side and factor:
Once you have factors whose product is zero, you can find the values of x that make those factors zero. A product can only be zero if one or more contributing factors is zero.
To solve 2x-5=0, you can add 5 then divide by 2:
... 2x -5 = 0
... 2x = 5
... x = 5/2
Answer:

Step-by-step explanation:
If Tim blows out one candle, there are 3 remaining. Then he blows another making 2 left. And finally he blows again leaving 1 left.
4x3x2x1 = 24.
There are 24 different ways to blow out his candle. We must multiply all the numbers together from greatest to least, and then we get the answer. The answer is 24.
