Answer:

see explanation

Step-by-step explanation:

Using the laws of logarithms

• log x - log y = log(\frac{x}{y})

• log_{b} x = n ⇔ x = b^{n}

Hence

log_{x}( \frac{8x-3}{4} ) = 2, hence

\frac{8x-3}{4} = x² ( multiply both sides by 4 )

8x - 3 = 4x² ← rearrange into standard form

Subtract 8x - 3 from both sides

4x² - 8x  + 3 = 0 ← in standard form

(2x - 1)(2x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = \frac{1}{2}

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = \frac{3}{2}
