Given Area:
35y²+13y-12
To Find :
Length and Breadth
Solution :
Factorising 35y²+13y-12
[By mid term spilting]
35y²+13y-12
35y²+28y-25y-12
7y(5y+4)-3(5y+4)
(5y+4) (7y-3)
Length = 7y-3
Breadth = 5y+4
35y²+13y-12
To Find :
Length and Breadth
Solution :
Factorising 35y²+13y-12
[By mid term spilting]
35y²+13y-12
35y²+28y-25y-12
7y(5y+4)-3(5y+4)
(5y+4) (7y-3)
Length = 7y-3
Breadth = 5y+4
