So you gave me the equation y equals x squared plus 2x plus 3.
00:07
Now, i don't know what you need to do with this equation, so we're gonna solve it.
00:11
Um, so i'm gonna start with trying to factor it.
00:13
What do i multiply to get 3 that adds to give me 2? well, i can multiply 1 times 3 to get 3.
00:20
Well, 1 plus 3 is 4.
00:23
That didn't give me 2.
00:25
Um, now i know i could get 2 with 3 and negative 1, but that gives me negative 3 when i multiply, so that doesn't work.
00:34
So this is not factual.
00:40
So now i'm gonna have to use the pythagorean theorem.
00:43
The pythagorean, i mean, not, shoot, the pythagorean theorem.
00:49
Oh my lord, i just solved a right triangle.
00:51
I apologize.
00:52
I'm gonna have to use the quadratic formula, x equals negative b plus or minus the square root of b squared minus 4ac all over 2a.
01:05
So x equals a equals 1, b is 2, and c is 3...
