The quadratic equations among the given options are:
(a) 3 x^2 + 11x + 10 = 0
(d) 2x^2 - √5x + 7 = 0
(f) x^2 - 3x = 0
(sorry, im asking again 'cause robot's reply is pretty bad.
Which of the following are quadratic equations?
(a) 3 x^2 + 11x + 10 = 0
(b) x + 1/x = 4
(c) x - 5/x = x^2
(d) 2x^2 - √5x + 7 = 0
(e) x^2 - √x - 5 = 0
(f) x^2 - 3x = 0
(g) x^2 + 1/x^2 = 3
(h) x (x + 1) - (x + 2) (x − 2) = -8
