The equations that are quadratic are:
(a) 3 x^2 + 11x + 10 = 0
(d) 2x^2 - √5x + 7 = 0
(f) x^2 - 3x = 0
(g) x^2 + 1/x^2 = 3
(a) 3 x^2 + 11x + 10 = 0
(d) 2x^2 - √5x + 7 = 0
(f) x^2 - 3x = 0
(g) x^2 + 1/x^2 = 3
how is g quadratic? it has x^2 as a denominator

Apologies for the confusion. You are correct, equation (g) is not quadratic due to the presence of x^2 as a denominator.
The corrected list of quadratic equations is:
(a) 3 x^2 + 11x + 10 = 0
(d) 2x^2 - √5x + 7 = 0
(f) x^2 - 3x = 0
The corrected list of quadratic equations is:
(a) 3 x^2 + 11x + 10 = 0
(d) 2x^2 - √5x + 7 = 0
(f) x^2 - 3x = 0
why is g accepted and not e?
