Question

4+{(-8)+25}={4+(-8)}+25 name the property​

Answer 1

Answer:

(a+b) square = a square + b square + 2ab

Answer 2

Step-by-step explanation:

Given that

4 + {(-8)+25} = { 4 + (-8)}+25

4 + { 17 } = { 4 - 8 } + 25

We know that ( + ) × ( - ) ===> ( - ) Or

( - ) × ( + ) ===> ( - )

"Remove brackets on both sides"

===> 4 + 17 = - 4 + 25

===> 21 = 21

We must use the

( a - b )2 = a2 - b2 + 2ab
