Step-by-step explanation:
Let two numbers be x and y and x(larger) y (smaller).
then, x^2-y^2 = 88 ----(2)
A/q ,
x = 2y - 5 ----(1)
Substitute value of x in given eqn 2,
(2y-5) ^2 -y^2 = 88
=>4y^2 + 25 - 20 y - y^2 = 88
=>3y^2 - 20y +25 -88 = 0
=> 3y^2 - 20y - 63 = 0
=>3y^2 - 27y +7y-63 =0
=>3y(y-9) +7(y-9) = 0
( 3y + 7)(y-9) = 0
=> y=9 ( right)
or, y = -7/3 (neglected)
Since Y=9,
Therefore,
x= 2*9 - 5 = 18 - 5 = 13
Hence,the required two numbers are 13 and 9.
