    SEMESTER I CI+BI AKSELERASI
     SMA NEGERI 2 BITUNG “RSBI”
     TAHUN PELAJARAN 2012/2013
Standard Competence :
Solve problems related to systems of linear equations
and linear inequalities of one variable.

Basic Competence :
Solving inequalities involving one variable of surds.

Indicator :
• Completting the surds inequality.
• Interpret issues related to the surds inequality.
SURDS INEQUALITY

Surds inequality is an inequality that the variable is in the surds.
Pertidaksamaan yang memuat bentuk akar adalah pertidaksamaan
yang variabelnya berada di dalam akar.



1.   Arrange both sides to balance (Susunlah kedua ruas hingga
     seimbang)
2.   Squared both sides (Kuadratkan kedua ruas)
3.   Completed the surd inequality (Selesaikan pertidaksamaan yang
     memuat bentuk akar)
SURDS INEQUALITY

To complete the surd inequality, The number in the surds must bigger
or equal to zero. ( ≥0 )
Untuk menyelesaikan pertidaksamaan yang memuat bentuk akar,
bilangan di dalam akar harus lebih besar atau sama dengan nol. ( ≥0 )




            f ( x)            g ( x ) haruslah
         f ( x)        0 dan g ( x )               0
EXAMPLE AND SOLUTION
TO COMPLETE SURDS INEQUALITY

    2x 6                   3 x 12
Solution :

syarat               pertidaksa maan :             syarat bentuk             akar :

GRAPHICS OF       2x       6   3x   12

                                         Syarat pertidaksamaan
                               6
                                         Syarat bentuk akar (1)
              3
                                         Syarat bentuk akar (2)
                       4


                                         Hasilnya
                               6         [Irisan          Syarat
                                         Pertidaksamaan,
                                         Syarat Bentuk Akar
              Jadi HP = { x | x > 6 }    (1), dan Syarat Bentuk
                                         Akar (2).]
