    x = 1/2

    Step-by-step explanation:

    Step 1: Isolate x's

    4x² - 4x + 1 = 0

    Step 2: GCF

    4 (x² - x + 1/4) = 0

    x² - x + 1/4 = 0

    Step 3: Factor

    (x - 1/2) ² = 0

    Step 4: Solve

    √ (x - 1/2) ² = √0

    x - 1/2 = 0

    x = 1/2

    And we have our final answer!

    X = 1/2

    Step-by-step explanation:

    Sub the value of x as 1/2

    4x² + 3 = 4x + 2

    4*1/4 + 3 = 2 + 2

    1 + 3 = 4

    4 = 4

    Hence the value of x is 1/2
