If you had in view of what it is an exponent that it turns out that:
X^2 + 8x + 15=0
D = 64-4*1*15=4
x1 =-8-2/2 =-5 x2 =-8+2/2 =-3
I think it is not necessary to speak at once that - yes you did not know it. I knew. But it was very important to understand to me that means * ^ * |
Ok.How many will be 2+2*2?
First you do 2+2=4 then you do 2*4 and you get 8 :)
You the great mathematician) But I will remind) By a mathematics rule - multiplication) goes the first |
First you do 2+2=4 then you do 2*4 and you get 8 :)
I'm starting to wonder how old you are. Multiplication goes before addition if there is no parentheses.
So:
2+2*2
=2+4
=6
X^2 + 8x + 15=0
D = 64-4*1*15=4
x1 =-8-2/2 =-5 x2 =-8+2/2 =-3
You have once again failed.
There are TWO answers that work on of which I believe you have stated.
x=-3 or x=-5 |
| *one of which I |
x1 =-8-2/2 =-5 x2 =-8+2/2 =-3
If you have not noticed - I have specified 2 values x |
| I haven't noticed, my apologies on that. Clean up your work, make the spaces bigger between the calculations of the two values. |
| To mine you simply to cling on trifles. It is good. Then also I will ask a question: What exactly should be made in your example? To solve or find a range of definition? |

To mine we in vain swear:) Let's be on friendly terms simply:) |
| I'm going to stop posting is this thread, it's quite hard to talk to a person who doesn't speak English and I can't really understand the English produced by your translator. |

If fairly too it is a pity to me, the translator at me not so good: ( |

Do not take offence. I think dispute always it is possible to construct out of the blue..... But then to rake consequences. Here in what a problem. |
| why dont you use the russian server? |
why dont you use the russian server?
Smart question. Yeah why dont you use the russian server? Don't tell us ure bored cuz the Russian Server is more advance and everyone understands u and plus ure level 12 there.(unless u copied another name which is highly possible ^^) |
| Wow , congratulating yourself for a shit :O... ill give 1/10.. |
| gratz, hey u gotta admit, its a pretty big step |
6/10 is simplified to 3/5
NO That simplifies into 1.5/2.5=7.5/1.25 |
7.5
Oops .75 |
