For one and only 1 real solution, the discriminant = 0 (see chart attached)
<span>So we know b^2-4ac=0 when the equation is in the format of ax^2+bx-c=0. Make sure your equation is in the right format first!</span>
<span>Given kx^2+12x-4=0 </span>
<span>b=12 </span>
<span>so b^2-4ac=0 </span>
<span>144 = 4ac </span>
<span>144 = 4(k)(-4) </span>
<span>144/(-16) = k </span>
<span>k = -9</span>
