Question

find the value of 4.75×4.75 × -2×4.75×5.75 × 5.75×5.75​

Answer 1

Step-by-step explanation:

Given that:-

4.75×4.75 × -2×4.75×5.75 × 5.75×5.75

=>(4.75)²-2(4.75)(5.75)+(5.75)²

This is in the form of a²-2ab+b²

Here, a=4.75 and b=5.75

We know that

a²-2ab+b²=(a-b)²

(4.75)²-2(4.75)(5.75)+(5.75)²

=>(4.75-5.75)²

=>(-1)²

=>1

4.75×4.75 × -2×4.75×5.75 × 5.75×5.75=1
