 Question 180322: TRANSLATE THE FOLLOWING INTO A QUADRATIC EQUATION AND SOLVE IT. THE LENGTH OF A RECTANGULAR GARDEN IS FOUR TIMES ITS WIDTH, IF THE AREA OF THE GARDEN IS 196 SQUARE METERS, WHAT ARE ITS DIMENSIONS? This is the answer that I got, please tell me what I did wrong.... Width is X Length is 4X Area is 196 X(4X) = 196 4X² = 196 subtract 196 from each side to get zero on one side 4X² - 196 = 0 (2X – 14)(2X +14) solve by factoring a difference of squares 2X - 14=0 2X + 14=0 solving the 2 equations separately 2X=14 2X= -14 X=7 X= -7 Check: x(4x) =196 7(4.7) =196 7(28) = 196 196 = 196 Dimensions of rectangle are: Width is 7 Length is 28 Click here to see answer by stanbon(57361)
