Question

the sum of two numbers is 30 and the difference of their square is 180. find the number​

Answer 1

the sum of two number is =30

the difference is 180 squad yes no

• now just add them

Answer 2

Answer:

let the no. be x and y,

then,

x+y = 30 .........(1)

and. x² -y² = 180

so , (x+y)(x-y) = 180

30× (x-y) = 180

(x-y) = 60.............(2)

hence, adding (1) and (2) ,

x+y +x-y = 30+40

2x = 70

so, x = 35.

and , y = -5
