What Is 9 Squared
What is a square (x9)? 3
x 2 18x + 81
Use the term (ab) 2 = a 2 + b 22ab.
9 square meters
The formula (a b) is square.
= a * 2 + b * 2 2ab
So let's assume that for the square of (x9)
= x * 2 + 81 2 {1} {9x
= x * 2 + 81 18x
This is the answer
(x9) 2 = (x9) (x9) = x 2 9x 9x +81 = x 2 18x + 81
Multiply x y (x9) or x (x9) first = x 2 9x.
Then first multiply 9 and (x9) or 9 (x9) = 9x + 81
Then you add the parts, x 2 9x 9x + 81
