## **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 For example, who helps #### **What Is 9 Squared** --- _[View the full topic](https://howtodiscuss.com/t/what-is-9-squared/85242)._
