Task 3 Order of Operations.docx Task 3 Finite Mathematics Task 3: Order of Operations A. Explain why 2 + 3(x ˆ’ 2) = 5x ˆ’ 10 is not true as a rule. This equation is not true as a rule ... because first you have to distribute the 3( x ˆ’2) , and when you do the equation reads 2 +3 x ˆ’6=5 x ˆ’ 10 . Next, you have to simplify the left- hand side of the equation by adding 2 to -6, making the equation read 3 x ˆ’4 =5 x ˆ’1 0 . Both sides of the equation are not equivalent, so as a rule, this is not true. B. Explain why (a + b)2 = a2 + b2 is not true as a rule. This equation is not true as a rule because first, you have to distribute the (a+ b)2 on the left-hand side, and when you do the equation reads ( a +b ) ( a +b )=a2 +b2 . When you use the FOIL Method to distribute, the equation will then read a2 +ab +ab+ b2=a 2+ b2 . Next, combine the like terms on the left to get a2 +2 ab + b2. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
