Question

write a pair of integer whose product is -36 and whose difference is 15

Answer 1

Step-by-step explanation:

let, one of the integer is =x

and another is = x + 15

according to the question...

x(x+15)=-36

or,x^2 +15x+ 36=0

or, x^2+12x+3x+36=0

or, x(x+12)+3(x+12)=0

or, (x+12)(x+3)=0

x+12=0. or x+3=0

or,x=-12. or x=-3

if x =-12 then x+15=3

if x=-3 then x+15=12.

hope it's helpful...
