Ty for your tips my score went up 50 points on math and got a 1250!
Yay!
Desmos is definitely a gamechanger!
All the videos start from you already knowing how to use it but you did a great job introducing how to enter small things like exponents which which I didn't know.This is the video for absolute beginners thanks btw.
Great video, very well explained. Thank you.
this helped me SO much THANK YOU 🙌🙌🙌🙌
Also, the reason for when you put with Zero and it doesn't show the graph is because putting zero means we are asking for the roots but that equation has imaginary roots that's why without 0 it gets graphed, i hope it is understandable what i wrote
You are correct! That's actually a really easy way of explaining what's going on!
Wait this is game changing. Why did nobody tell me about this
this is fantastic mate! thanks so muchh!! big help
thank you!!!!!!
this is really helpful.thank you :)
It's not that desmos has some sort of initial distaste towards some of your equations, it's the fact that they are one variable equations without y values.

How can you solve the last question without a calculator?
Both are set up as y = , so they must equal each other, so set them equal to each other, giving you 2x^2-21x+64=3x+a. Now get everything to one side and you get . Because they say these intersect in exactly one point, that's equivalent to saying that the of the quadratic formula is equal to 0. The discriminant is the part under the radical in the quadratic formula, b^2 - 4ac. (By the way, two solutions means discriminant is > 0, no solutions means discriminant is < 0). Now use the coefficients of this quadratic as our a, b, and c to plug into the discriminant, which we set equal to 0. a= = 2, b = -24, c = 64 - a. So b^2 - 4ac = 0 will become (-24)^2 - 4(2)(64 - a) = 0, which becomes 576 - 512 + 8a = 0, which becomes 64 + 8a = 0, or 8a = -64, so a = -8. But we need to find x, so we plug this back in for a to get 2x^2-24x+64-(-8)=0, or 2x^2-24x+64+8=0, or 2x^2-24x+72=0. Now divide all by 2 to get x^2-12x+36=0, which factors to (x-6)(x-6)=0, so x-6=0 and . Wow. That was long!!!!
thanksss@@Methodtestprep
🔥🔥🔥🔥
What is a SAT? Never seen one in my life...
thank you beautiful man
y add the music hhhhhhhhhhhhhhhhhhhhhh
bruh =0 doesnt graph because the solutions are non-real!!
