Y = k/x where k is the constant of variation
y = 3 , x = 1.2 gives
3 = k/1.2
therefore
k = 3*1.2 = 3.6
and the required equation is

y = 3.6 / x

What is x^4-10x^2+9 simplified

Zanzabum

$\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\
%x^4-10x^2+9 
x^4-10x^2+9\implies (x^2)^2-10x^2+9\implies (x^2-9)(x^2-1)
\\\\\\
\underline{(x^2-3^2)}(x^2-1^2)\implies \underline{(x-3)(x+3)}(x-1)(x+1)$

$\bf \textit{keep in mind that }1=1^2=1^3=1^5=1^{10}=1^{1000000}$
