Question

Solve for x.
16x squared - 81 = 0

Answer 1

To solve for x, we first need to rewrite the equation in standard form:

16x^2 - 81 = 0

Next, we can factor the equation as a difference of squares:

(4x + 9)(4x - 9) = 0

Now, we can set each factor equal to zero and solve for x:

4x + 9 = 0
4x = -9
x = -9/4

4x - 9 = 0
4x = 9
x = 9/4

Therefore, the solutions for x are x = -9/4 and x = 9/4.
