My Notes + Ask Your Teacher Students frequently perform the following type of calculation to introduce a zero into a matrix. 4 1 4R2 - 3R1 3 6 [8 27 ] However, 4R2 - 3R1 is not an elementary row operation. Why not? O 4R2 - 3R1 is not an elementary row operation since it does not include the interchanging of two rows. 4R2 - 3R1 is not an elementary row operation since the coefficient of R1 is 3. 4R2 - 3R1 is not an elementary row operation since the coefficient of R1 is -4. 4R2 - 3R1 is not an elementary row operation since the coefficient of R2 is 4. 4R2 - 3R1 is not an elementary row operation since the coefficient of R2 is -3. Show how to achieve the same result using elementary row operations. Perform the elementary row operation R2 - - R1. Perform the elementary row operation R2 - SR1 . O First perform the elementary row operation R2 - -R1, then perform 4R2. First perform the elementary row operation R2 - -R1, then perform 3R2. First perform the elementary row operation R2 - 3R1, then perform 4R2. Need Help? Read It Talk to a Tutor4. -/1 points PooleLinAlg4 2.2.030.
