Question

The integers differ by 12 and the sum of their squares is 74.

Answer 1

let x and y be the integers

x - y = 12

x^2 + y^2 = 74

solve for x and y

does that help?

Answer 2

x^2+y^2=74 then (y+12)^2+y^2=74 but how do i dothe next step?

Answer 3

expand (y+12)^2

Answer 4

use (a+b)^2=a^2+b^+2ab where a=y and b=12 now put into equ.

Answer 5

use (a+b)^2=a^2+b^2+2ab where a=y and b=12 now put into equ.
