I have the term 2x^2-x-3 and want to apply pq formula so I halve everything
then have x^2-0.5x-1.5
Then why do the zeros always change when it becomes 1x^n?
For example, if I have 4x^2-2x-6, are the zeros identical?

Loading...Are there any problems with an infinitely large resistance from an electrical engineering point of view, for example if the capacitance becomes small at the same time?
I'm taking my Abitur math exam in Bavaria on Monday, and since my ancient calculator is missing a few important functions, I borrowed one from a friend. It's not the standard calculator at our school, and it has a few functions that seem too advanced for the Abitur. I haven't found much information about it…
Can anyone help me with this task? Two trains are facing each other on adjacent tracks. After initially being 40 m apart, they both start moving simultaneously and move toward each other. The left train accelerates uniformly at 1.4 m/s^2, and the right train accelerates at 2.2 m/s^2. How far does the left train travel…
Need help with a math problem. 1 + 3. What is this? Please hurry?????!!!!!!!!!!!!!№
Here is an example: y = (x + 2)² + 5 (-2|5)
cos^2(x) / sin^2(x) = 1/tan^2(x) and cos(x)/sin(x) = 1/tan(x) ???
… The zero points must not change (and do not do it), otherwise the division by 2 would not be allowed. Or otherwise:
If pq formula and abc formula (aka: midnight formula) do not deliver the same result for zero points, then something went wrong in one of the two invoices.
have you been writing off?
2x^2-x-3
x2 – 0.5x – 1.5 = 0
you have divided 2
you take x2 – 0.5x – 1.5 times 4 you have the same zeros because you have to split by 4
