ORDER OF OPERATIONS A umerical expressio must have exactly oe value, to e determied y the order of operatios. Groupig Symols: Evaluate expressios iside groupig symols, such as paretheses, rackets a, races, ad fractio ars, such as i. c Expoets: Evaluate all powers. Multiplicatio ad Divisio: Perform these operatios with equal importace from left to right. Note: a commo miscoceptio is that multiplicatio is always performed efore divisio. These operatios rak equally, ad oly the order i which they appear determies the order i which they are performed. For example, the expressio 18 simplifies to 7. Additio ad Sutractio: Perform these operatios with equal importace from left to right.

SOLVING ABSOLUTE VALUE EQUATIONS AND INEQUALITIES The asolute value of a umer is its distace away from 0 o the umer lie. Sice distace is oegative, the asolute value of a umer is always oegative. uits uits For example, if x the we kow that either x or x. - 0 Solve each of the followig equatios. Report your aswers i simplest form.. x. x 8. x 17 11 6. x 0 9 7. x 1 9 8. x 1 To solve a asolute value iequality, we ca still use the defiitio of a asolute value from aove.

FACTORING POLYNOMIALS Guidelies for Factorig: Always look for a GCF efore doig aythig else. Cosider the umer of terms i the polyomial. Two Terms: Try factorig as a differece of two squares. a a a Three Terms: Triomials of the form ax x c ca e factored ito the product of two iomials. (Use a method that your Algera 1 teacher taught you.) More Tha Three Terms: Try factorig y groupig. Make sure the polyomial is factored completely. This meas that each remaiig factor is prime. Factor each of the followig expressios completely. 98. x 8x 99. x 1x 6 100. x 0x 8 101. x 0x 8 10. x x 6 10. 9a 6 10. x x 9x 18 10. x x 1 106. x 1x 18 107. ac ad c 6d 108. 6x 7x 109. x x 1 110. 1x 1x 111. 8a a
