![18 {u}^{2} - 50y \\ \\ = 2[9 {u}^{2} - 25y] \\ \\ = 2[(3 {u})^{2} - (5 \sqrt{y} )^{2} ] \\ \\ = 2(3u + 5 \sqrt{y} )(3u - 5 \sqrt{y} )](https://tex.z-dn.net/?f=18%20%7Bu%7D%5E%7B2%7D%20%20-%2050y%20%5C%5C%20%20%5C%5C%20%20%3D%202%5B9%20%7Bu%7D%5E%7B2%7D%20%20-%2025y%5D%20%20%5C%5C%20%20%5C%5C%20%20%3D%202%5B%283%20%7Bu%7D%29%5E%7B2%7D%20%20-%20%285%20%5Csqrt%7By%7D%20%29%5E%7B2%7D%20%5D%20%20%20%5C%5C%20%20%5C%5C%20%20%3D%202%283u%20%20%2B%205%20%5Csqrt%7By%7D%20%29%283u%20-%205%20%5Csqrt%7By%7D%20%29)
Answer:
1/2 lemonade -> 2 water
3 lemonade -> ? water
x * 1/2 = 3*2
x/2 = 6
x=12
Step-by-step explanation:
Answer:
(x+1)(x-1)
Step-by-step explanation:
The solutions 1 and - 1 is given when
x = 1 or x = - 1
hence; (x - 1) = 0 or (x + 1) = 0
(x - 1)(x + 1) = 0
x² -1 = 0
