Question

What is the positive solution to the equation 64x2 + 12x = 1.

Answer 1

Answer:

1/16

Step-by-step explanation:

Here: 64x^2+12x = 1

Then, 64x^2 +12x -1=0

The delta = 12^2 - 4*64*(-1)= 400 = 20^2

These two solutions are:

(-12+20)/(2*64)=  8/(2*8*8)= 1/16

(-12-20)/(2*64) but this is negatif.

1/16 is the positif solution.

Hope that useful for you.
