Question

2.86* 2.86 * 2.86 + 2.14* 2.14*2.14 / 2.86 * 2.86 - 2.86 * 2.14+ 2.14*2.14 factorisation

Answer 1

Answer:

5

Step-by-step explanation:

let 2.86 = x

and 2.14 = y

x^3 + y^3 / x^2 - xy + y^2

= (x+y)(x^2 - xy + y^2) / (x^2 - xy + y^2)

= x+y

On re-substituting values of x and y we get,

2.86 + 2.14

=5
