Chapter 13 Membrane Channels and Pumps Figure The flow of ions through a single membrane channel (channels are shown in red in the illustration at the left) can be detected by the patch clamp technique, which records current changes as the channel transits between the open and closed states.
Jawaban Terbaik: You start by factoring the 2x^2: (2x + .....) (x + .....) Then you factor the -3 into -1 and 3, and put it in the parentheses: (2x - 1) (x + 3) Now multiply it out to check: 2x^2 -x +6x - 3 = 2x^2 + 5x - 3 So, the answer is (2x - 1) (x + 3).aporkan Penyalahgunaan. What you have to realize is that now instead of factoring x^2 into x and x, you're now factoring 2x^2 into 2x and x. If you look at your outside terms, 2x^2 only has 2 possible factors (2x and x), and 3 only has 2 possible factors (3 and 1).
The 4x is a negative 4x, because it is subtracted, so you can't add 5x to it and get -9x, you actually get 1x (since -4 + 5 is 1). You can think of it as 3x + 2x + (-4x) + 5x and work it that way.BTW, when it comes to addition and subtraction, it does not matter what order you do it in, but you can typically just do them both left to right (whichever comes first). E.G.: You take the 3x, add the 2x, subtract the 4x, add the 5x, ect.ou're adding -4x and +5x here, so it should be x instead of -9x. If the original equation was 3x + 2x - (4x + 5x) = 20, then your solution would be valid. Sleeper_9 said: I always learned that order of operations says that you do all the addition before the subtraction. so 5x - 9x = 20.
