Question

give possible ecpressions for the length and breadth of rectangle having 35x²+13x-12 as its area
​

Answer 1

area=35y^2+13y-12

factorising 35y^2+13y-12

(by mid term splitting)

35y^2+13y-12

35y2+28y-25y-12

7y(5y+4)-3(5y+4)

(5y+4) (7y-3)

length=7y-3

breadth= 5y+4

hope it helps you
