Find a value of k such that kx2 + 12x − 4 = 0 has one real-number solution. Explain.

if x is to the 2 power then

kx^2+12x-4=0         Add 4 to the both sides

kx^2+12x=4             Divide both sides by 12

kx^2=1/3x                square root the both sides

k=0.6x

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
