We need to factorize this trinomial.
00:03
So let us first take out x -risk -reveyor -of -4 -s common from all of them.
00:08
So we have 2x squared negative 5x -negative 3.
00:17
Now we just need to factorize this trinomial using splitting middle -term method.
00:23
We want to split this 5 right now.
00:26
So to decide whether to use addition or subtraction, we compare it with a x squared plus bx plus c.
00:33
We get the value of as2.
00:36
B is negative 5 and the c is negative 3.
00:40
We multiply a times c.
00:43
That's a negative number, as you see.
00:45
It's negative 6.
00:46
Therefore, we use a negative sign to split this 5.
00:51
So to get that 5 from that, let us now factorize of 06.
00:57
As we factorize it, we get these many patterns, like these only numbers, so we can write 6 negative 1.
01:05
That's equivalent to 5, and that works for that.
01:09
So it's x -rays to the power of 4...
