Week 6 in precalc 11
This week in math 11 I learned about the quadratic formula.
the quadratic formula looks like this :
in order to fill in the variables you need to know what is what.
so when you’re looking at an equation it will look like
a + bx + c = 0.
your a variable is obviously the number in front of the but if there is no number in front of it, a = 1. b is the second variable and it is the one in the middle of the equation and c is separate on its own.
It takes more time then completing the square and factoring but it is a good way to get the correct answer since you fill in all the variables and get a more direct answer.
