ktoś ma pomysł ?
| √12+4x2−4 | √12+4x2−4 | √12+4x2+4 | |||
= | * | ||||
| x−1 | x−1 | √12+4x2+4 |
| 12+4x2−16 | ||
= | ||
| (x−1)(√12+4x2+4) |
| −4+4x2 | ||
= | ||
| (x−1)(√12+4x2+4) |
| 4(x2−1) | ||
= | ||
| (x−1)(√12+4x2+4) |
| 4(x−1)(x+1) | ||
= | ||
| (x−1)(√12+4x2+4) |
| 4(x+1) | 4*2 | 8 | ||||
= | → | = | =1 gdy x→1 | |||
| (√12+4x2+4) | √16+4 | 8 |
!
zapomniałem licznika rozłożyć
super, pozdrawiam
