Question

Split 10 into two parts so that difference between the squares of the parts is 60.
Split N into two parts so that the difference between the squares of the parts
is D.

Answer 1

Answer:

Step-by-step explanation:

x+y=10--- 1

x²-y²=60 --- 2

From equation 2, (x+y)(x-y)=60--- 3

we know that (x+y) = 10

Therefore, equation 3 is,

10(x-y)=60

divide both sides by 10

(x-y) =6

we now have a simultaneous equation.

x+y = 10

x-y= 6

solving simultaneously,

x=8 and y= 2
