Problem we need to solve our equation using the quadratic formula.
00:08
Our equation is in standard form, so we just need to label a, b, and c.
00:13
So, ax squared, plus bx plus c, our a, right here is 1, our b is negative 6, and our c is 10.
00:27
So we're going to substitute that information into our equation, our quadratic formula, opposite of b, so i have negative 6, so i'm going to put positive 6, plus or minus the square root of negative 6 squared, right? this is b, isn't it opposite b anymore, minus 4 times 1 times our c, which is 10.
01:01
That is all divided by 2 times 1.
01:07
So when we clean this up, we're going to have 6 plus or minus the square root.
01:13
Negative 6 squared is going to be positive 36 minus 4 times 1 is 4...
