Q. Find one value of x x that is a solution to the equation:\newline(4x1)2=20x5 (4 x-1)^{2}=20 x-5 \newlinex= x=
  1. Expand squared term: Expand the squared term on the left side of the equation.\newline(4x1)2=(4x1)(4x1)=16x24x4x+1(4x - 1)^2 = (4x - 1)(4x - 1) = 16x^2 - 4x - 4x + 1\newlineCombine like terms.\newline16x28x+1=20x516x^2 - 8x + 1 = 20x - 5
  2. Combine like terms: Move all terms to one side to set the equation to zero.\newline16x28x+120x+5=016x^2 - 8x + 1 - 20x + 5 = 0\newlineCombine like terms.\newline16x228x+6=016x^2 - 28x + 6 = 0
  3. Move terms to one side: Factor the quadratic equation, if possible.\newlineThis step involves finding two numbers that multiply to 16×6=9616 \times 6 = 96 and add up to 28-28. However, since 9696 is not easily factored into two numbers that add up to 28-28, we might need to use the quadratic formula to find the roots.
  4. Factor quadratic equation: Use the quadratic formula to find the values of xx. The quadratic formula is x=b±b24ac2ax = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}, where a=16a = 16, b=28b = -28, and c=6c = 6. Calculate the discriminant: b24ac=(28)24(16)(6)=784384=400b^2 - 4ac = (-28)^2 - 4(16)(6) = 784 - 384 = 400
  5. Use quadratic formula: Calculate the square root of the discriminant. 400=20\sqrt{400} = 20
  6. Calculate discriminant: Plug the values into the quadratic formula.\newlinex = (28)±20216\frac{{-(-28) \pm \sqrt{20}}}{{2 \cdot 16}}\newlinex = 28±2032\frac{{28 \pm \sqrt{20}}}{{32}}
  7. Calculate square root: Solve for the two possible values of xx.
    x=28+2032x = \frac{28 + 20}{32} or x=282032x = \frac{28 - 20}{32}
    x=4832x = \frac{48}{32} or x=832x = \frac{8}{32}
    Simplify the fractions.
    x=32x = \frac{3}{2} or x=14x = \frac{1}{4}
  8. Plug values into formula: Choose one value of xx as the solution.\newlineWe can choose either x=32x = \frac{3}{2} or x=14x = \frac{1}{4} as the solution to the equation. Let's choose x=32x = \frac{3}{2} for this prompt.
