Answer:
. so, suppose for (x-9)squared. = x*2 + 81 - 2 {1} {9x} = x*2 + 81 -18x. that's the answer.
Step-by-step explanation:
the formula is (a - b) squared. = a*2 + b*2 - 2ab.
The required value of the square of x - 9 is x² - 18x + 81.
Given that,
What is x – 9 squared is to be determined.
In mathematics, it deals with numbers of operations according to the statements.
The methodology in mathematics to employ and analyze the function or expression to make the function or expression superficial or more intelligible is called simplifying and the process is called simplification.
Here,
Square of (x - 9)
= (x - 9)²
= (x - 9)(x - 9)
= x² - 9x - 9x + 81
= x² -18x + 81
Thus, the required value of the square of x - 9 is x² - 18x + 81.
