Given
[tex]f(x)=x^2-8x[/tex]
To find the standard form of the quadratic equation.
Explanation:
It is given that,
[tex]f(x)=x^2-8x[/tex]
That implies,
[tex]\begin{gathered} f(x)=(x-4)^2-4^2(by\text{ completing the square method}) \\ =(x-4)^2-16 \end{gathered}[/tex]
Hence, the standard form of the quadratic equation is,
[tex]f(x)=(x-4)^2-16[/tex]
