For the very first one, we're going to combine those log functions together.
00:04
So when i put them together, i'm going to foil that because it's multiplying with the kids of that addition.
00:09
So x times x squared, outside inside gets negative 6x, and 2 times negative 8.
00:15
That's equal to 3.
00:17
So that we're stuck, we're going to convert.
00:18
It becomes x squared minus x minus x minus 15 equals the base 3 to the third power, which is 27.
00:26
So now i'm going to subtract the 27 to the other side.
00:29
So negative 16 minus 27 is 43.
00:33
So i have x squared minus 6x minus 43 is equal to zero.
00:42
So we have no factors of 43 that's going to add up to negative 6 there.
00:50
So we're going to do some quadrant formula to x.
00:53
So that'll be x is equal to opposite b.
00:57
2 % of d .p squared, 24, 5, 8.
01:02
Times c and then all over two times a, which would be two.
01:07
Then my preference is to simplify what underneath a square root.
01:09
So doing for the six minus four times one times that negative 43.
01:14
And i get 208.
01:15
So six plus or minus the square root of 08 all over two.
01:20
So we get two answers here.
01:22
Just upon the on what you do first.
01:24
So to six plus the square root of 208...
