Question

3(s-5)/4 -3 = 4s- (s-3)/2
pls answer fast​

Answer 1

`s = (9± √( - 39) )/(4)`

Explanation:

`(3(s - 5))/(4 - 3) = (4s * (s - 3))/(2)`

➡️
`(3(s - 5))/(1) = 2s * (s - 3)`

➡️
`3s - 15 = 2 {s}^(2) - 6s`

➡️
`3s - 15 - 2 {s}^(2) + 6s = 0`

➡️
`9s - 15 - 2 {s}^(2) = 0`

➡️
`- 2 {s}^(2) + 9s - 15 = 0`

➡️
`2 {s}^(2) - 9s + 15 = 0`

➡️
`s = \frac{ - ( - 9)± \sqrt{( - 9 {)}^(2) - 4 * 2 * 15} }{2 * 2}`

➡️
`s = (9± √(81 - 120) )/(4)`

➡️
`s = (9± √( - 39) )/(4)`

➡️
`s∉ℝ`
