My current math teacher is probably one of the best math teachers there are, even amongst social media mathematicians who make sound guides. Alas, my teacher doesn’t make any video guides and have notes that are, for me, hard to follow. So the only way I can learn is by focusing in class which my absent and mathematically impaired mind is not too good at. I have to sporadically seek UA-cam guides as a result, lol.
Again, doing a better job explaining this than my math teacher. Left my math class today being totally confused, couldn't figure out the homework, came here, now it's game on for the homework!
this is kinda late, but he does have another video about 30 minutes explaining all the basics. you should watch that and then watch this one. it should clear things up :)

@@ZOMBIE_NOTFOUND Bring the 2x term over to the left side by subtracting it from both sides. 5x² = 2x + 1 becomes 5x² - 2x = 1 Take the 5 out 5x² - 2x = 1 becomes 5(x² - (2/5)x) = 1 we can simplify this again by dividing both sides by 5 5(x² - (2/5)x) = 1 becomes x² - (2/5)x = 1/5 Now you have it in the form you want. Take the -2/5, half it and square it, then add to both sides. -2/5 halfed is -1/5. This -1/5 is the term we want inside the brackets. Squaring that gives (-1/5)^2 = 1/25. So add 1/25 to both sides. x² - (2/5)x = 1/5 x² - (2/5)x + 1/25 = 1/5 + 1/25 (x - 1/5)² = 1/5 + 1/25 We can simplify the right side by making them have a common denominator. 1/5 = 5/25. so 1/5 + 1/25 = 5/25 + 1/25 = 6/25 (x - 1/5)² = 1/5 + 1/25 (x - 1/5)² = 5/25 + 1/25 (x - 1/5)² = 6/25 Square root both sides. (x - 1/5)² = 6/25 x - 1/5 = ± sqrt(6/25) x - 1/5 = ± sqrt(6)/5 Add 1/5 to both sides x - 1/5 = ± sqrt(6)/5 x = ± sqrt(6)/5 + 1/5 x = (± sqrt(6) + 1)/5 Not the best way to solve an equation like that but I hope it helps.

Just copy over the number outside the brackets, in this case the number is 2. Then copy the x and the last number in the bracket, but don’t copy it with ^2. Only put the ^2 outside the brackets
in order to complete the square, you have to take the middle coefficient (in this case, 5/3) and divide it by 2 and then square it. That would make it ((5/3) x (1/2))^2. This equald (5/6)^2. Hope that helps :)

like 5x²=2x+1 how to solve this?
@@ZOMBIE_NOTFOUND Bring the 2x term over to the left side by subtracting it from both sides.
5x² = 2x + 1 becomes
5x² - 2x = 1
Take the 5 out
5x² - 2x = 1 becomes
5(x² - (2/5)x) = 1
we can simplify this again by dividing both sides by 5
5(x² - (2/5)x) = 1 becomes
x² - (2/5)x = 1/5
Now you have it in the form you want. Take the -2/5, half it and square it, then add to both sides. -2/5 halfed is -1/5. This -1/5 is the term we want inside the brackets. Squaring that gives (-1/5)^2 = 1/25. So add 1/25 to both sides.

(x - 1/5)² = 1/5 + 1/25
We can simplify the right side by making them have a common denominator. 1/5 = 5/25. so 1/5 + 1/25 = 5/25 + 1/25 = 6/25
(x - 1/5)² = 1/5 + 1/25
(x - 1/5)² = 5/25 + 1/25
(x - 1/5)² = 6/25
Square root both sides.
(x - 1/5)² = 6/25
x - 1/5 = ± sqrt(6/25)
x - 1/5 = ± sqrt(6)/5
Add 1/5 to both sides
x - 1/5 = ± sqrt(6)/5
x = ± sqrt(6)/5 + 1/5
x = (± sqrt(6) + 1)/5
