We're being asked to simplify the given expression.
00:03
To do this, first, let's simplify inside our brackets by using distributed property.
00:07
So at first, i'm going to bring down the 7 minus 4 and then our bracket.
00:12
So let's first distribute the 2.
00:13
Well, 2 times 3 is 6, and 2 times negative 2x is negative 4x.
00:20
And now we have to distribute the negative 5.
00:22
Well, negative 5 times 4x is negative 20x, and negative 5 times negative 3 is positive 15.
00:30
Now, we can get rid of our brackets by distributing the negative 4.
00:34
So i'm going to bring down the 7.
00:36
So now let's distribute.
00:38
Well, negative 4 times 6 is negative 24...
