The Disappearing Quadratic

CBSE Class 10 · Solve it one decision at a time. A wrong pick earns a nudge, never the answer.

Step 1 of 6

The problem

Find the value(s) of kk for which the equation (k−12)x2+2(k−12)x+2=0(k - 12)x^2 + 2(k - 12)x + 2 = 0 has real and equal roots.

Step 1 · Your move

Before the guided steps, what value did you get for kk?

(k−12)x2+2(k−12)x+2=0(k - 12)x^2 + 2(k - 12)x + 2 = 0
