Answer:
THE CORRECT OPTION IS "[tex]12 x^{2} + 8x^{1} -1[/tex] "
Step-by-step explanation:
The quadratic equation is defined as equation having degree 2.
The standard form of quadratic equation is :
[tex]ax^{2} +bx+c[/tex].
where a, b, c are numbers and a cannot be equal to zero.
From the above statements we can say that "[tex]12 x^{2} + 8x^{1} -1[/tex] " is quadratic equations and rest options does not qualify the equations of quadratic equations.
