if the area of a rectangular field is represented by 2x^2-x-15 then find the length and breadth of the field
Asked by jaswanthsompi12345 | 19 Dec, 2023, 06:54: PM
Expert Answer
Area = 2x2 -x -15
Let us factorise above polynomial
2 × (-15 ) = -30 ; -6 × 5 = -30 ; -6+5 = -1
2x2 -6x +5x -15
2x(x-3) +5(x-3)
(x-3)(2x+5)
Hence , we can say that area has length (2x+5) and breadth (x-3 )
