Answer:


x=(\pm√(29) +1)/(4)

Explanation:

Quadratic Formula:
x=(-b \pm√(b^2-4ac) )/(2a)

Step 1: Write quadratic equation

4x² - 2x = 7

Step 2: Solve for x

  1. Move everything to one side: 4x² - 2x - 7 = 0
  2. Define variables: a = 4, b = -2, c = -7
  3. Plug into quadratic formula:
    x=(-(-2) \pm√((-2)^2-4(4)(-7)) )/(2(4))
  4. Evaluate for x:
    x=(\pm√(29) +1)/(4)
