Question

Using the property of squares find the value of the following 24 square - 23 square

Answer 1

47

Explanation:

Lets say 24 is x and 23 is y.

the equation would be x^2 - y^2

this is = to (x-y)(x+y)

substitute the numbers in

(24-23)(24+23)

which simplifies to

(1)(47)

which equals 47

Answer 2

47

Explanation:

Using the follwing property

`x^(2) -y^2=(x+y)(x-y)`

in which x=24 and y=23

so

`24^2-23^2=(24-23)(24+23)\\=1(47)\\=47`
