Explanation:

step 1: note down the given quadratic equation and compare it with the standard form ax2 + bx + c

so from the equation given

a = 1

b = k -3

c = 3-2k

step 2: look at the hints given in the question and according to the hints choose the discrimination (b2- 4ac) of the equation

1) b2 - 4ac > 0 (positive), there are 2 real solutions

2) b2 - 4ac = 0 (zero), there is one real solution

3) b2 - 4ac < 0 (negative) , there are 2 complex solutions or no real roots

step 3

substitute the values of a,b and c in the suitable discrimination i.e b2 - 4ac > 0

(k-3)2 - 4(1)(3-2k) > 0

(k2 + 9) - (12-8k) > 0

k2 + 9 - 12 + 8k

k2 - 3 + 8k

that is k2 + 8k - 3

a) K does not satisfy the equation
