(A) x2 + 2x + 1 = (4 – x)2 + 3 (B) –2x2 = (5 – x)(2x-(2/5))
(C) (k + 1) x2 + (3/2) x = 7, where k = –1 (D) x3 – x2 = (x – 1)3
(D)
Clarification:
The standard type of a quadratic condition is given by,
(A) Given,
which is certifiably not a quadratic condition.
(B) Given,
which is certainly not a quadratic condition.
(C) Given,
, where k = – 1
which is anything but a quadratic condition.
(D) Given,
which addresses a quadratic condition.
