Answer:
Here you go brother:)
The examples:
1). X=3 or x=4
I used the Desmos calculator after doing the math on a sheet of paper again, and both my answers and the answers on the slide thingy are right.
2). X=0 or x=3
Again, I used Desmos and I also did the equation by hand and they both came out with the same answer. Then I cross checked and they both have the same answer.
3). X=-5 or x=5
First I plugged in the equation, and then I solved the equation, and I got the same answer as the slide. I then punched it into the Desmos calculator, in which I got the same answer as the slide both times.
The do it yourself part:
a=3
b=-6
c=1
x=(-b±√(b^2-4ac))/2a
x=(6±√(36-12))/(6)
x=(6±√(24))/(6)
x=(6±2√(6))/(6)
x=(3±√(6))/(3)
x≈1.82
x≈.184
Now enter it into word or power point and then wa la, it's as simple as 123, NOT!!
Step-by-step explanation:
I am on the same thing, took me like five hours too find the stupid thing they were talking about. I'm bit special.
