All right, so with a profit equation being p equal to 17 times x1 plus x2, then minus c1, which is 0 .02x1 squared, plus 2x100, and then minus c2, which is 0 .05x2 squared, plus 2 ,000, and then minus c2, which is 0 .05x2 squared.
00:34
Squared plus 2 x2 plus 475 we want to try to maximize profit so let's simplify this sum so 17 x1 plus 17 x2 minus 0 .02 x1 squared and then we're going to combine some like terms so the x1s we just have 15 x1, the x2s.
01:31
That's 15 x2.
01:40
And then we can combine the constants.
01:51
So that's negative 700 minus 475.
02:00
Now just give us negative 1175.
02:04
So let's find the partial to respect to each variable.
02:08
So the partial 2 respect to x1 would give us 15...
