1/6

Step - 1: Get into the standard form.

Then the above equation becomes 36n2 - 12n + 1= 0.

Step - 2: Compare the equation with ax2 + bx + c = 0 and find the values of a, b, and c.

Then we get a = 36, b = -12. and c = 1.

Step - 3: Substitute the values into the quadratic formula which says x = [-b ± √(b² - 4ac)] / (2a). Then we get

x = [-(-12) ± √((-12)² - 4(36)(1))] / (2(36))

Step - 4: Simplify.

x = [ 12± √(144 - 144) ] / 72

= 12/72

= 1/6
