Problem

Solve the equation. \[ 36 x^{2}-1=0 \]

Solution

Step 1 :The given equation is \(36x^{2}-1=0\).

Step 2 :This is a quadratic equation in the form of \(ax^{2} + bx + c = 0\).

Step 3 :We can solve it by using the quadratic formula \(x = [-b ± sqrt(b^{2} - 4ac)] / 2a\).

Step 4 :However, in this case, the equation is a special case of quadratic equation, which is a difference of squares.

Step 5 :It can be factored into \((6x - 1)(6x + 1) = 0\).

Step 6 :We can solve for x by setting each factor equal to zero.

Step 7 :The solutions to the equation are \(\boxed{-\frac{1}{6}}\) and \(\boxed{\frac{1}{6}}\).
