Question

Find two numbers whose sum is 34 and product is 128

Answer 1

 x+z=34
x=34-z=======>(1)
          ;(also)
x×z= 128 =====>(2)
this is the method to solve

Answer 2

let nos be x,34-x
x*34-x=128
expand x[34-x]
=34x-xsquare=128

its a quadratic equation
now find factors of 128
i.e.2 and 64
4 and 32
8 and 16
so  there are no numbers whose sum is 34 and product is 128
