Okay, the question reads 7 z squared plus 23 z plus 6 over z squared plus 2 z minus 3.
00:13
Yeah, okay, so you can first start by simplifying the numerator.
00:18
So let's start off by multiplying the 7 to the 6.
00:23
So z square plus 23 z plus 42.
00:34
Okay, and then, oh, the 7 z is ready there, so you just rewrite the 7 z.
00:44
And then same thing on the other side, 7c.
00:49
And it's plus plus, because these operations are plus and plus, so you write plus plus plus.
00:58
And two numbers are multiplied to give you 42, but acting be 23 are 21 and 2.
01:06
Because 21 times 2 gives you 42 and 21 plus 2 gives you 23...
