The value of given expression is 3
Solution:
Given that we have to simplify the given expression and find its value when x = 0.97
Given expression is:
[tex](x - 10)^2 - x(x + 80)[/tex]
Multiply "x" with terms inside bracket
[tex]\rightarrow (x-10)^2-x^2-80x[/tex]
Substitute x = 0.97
[tex]\rightarrow (0.97-10)^2-(0.97)^2-80(0.97)\\\\\rightarrow (-9.03)^2-0.9409 - 77.6\\\\\rightarrow 81.5409 - 0.9409 - 77.6\\\\\rightarrow 80.6 -77.6 = 3[/tex]
Thus value of given expression is 3
