If 4 times a number is decreased by 3 and this difference is squared, the result is 9. find the numbers

x = 3/2 or 0

Step-by-step explanation:

let the number be x

"4 times a number" : 4x

"4 times a number is decreased by 3" : 4x -3

"this difference is squared" : (4x -3)²

"the result is 9" : (4x -3)² = 9    (solve this equation for x)

(4x -3)² = 9   (square root of both sides)

4x-3 = ±√9

4x-3 = ±3  (add 3 to both sides)

4x = ±3 + 3

Hence

4x = 3 + 3 = 6 > x = 6/4=3/2

or

4x = -3 + 3 = 0 > x = 0

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
