Okay, we're gonna combine the x terms and then the y terms, of course, by factoring out the constant in front of them, like this.
00:20
And then, so what do i add here? i add 1 here, and i add 125, right? so what did i add? i add 3 plus 250, so i actually have 253.
00:45
Okay, so then this is gonna be 3 times x plus 1 squared, and this is gonna be 10 times y minus 5 squared, which is equal to 30.
01:01
And divide everything by 30, so you will have x plus 1 squared is over 10, plus y minus 5 squared, 3 is equal to 1.
01:19
Okay? okay, so this is a horizontal one, because root 10 squared of 10 is bigger than square root of 3.

Alright, not bad, huh? yep, that's a good ellipse...
