Q. Solve the equation. Check your solutions. Write your solutions from least to greatest, separated by a comma, if necessary.\newlinex212=8x-x^{2}-12=-8 x\newlinex=,x = \square , \square
  1. Rewrite Equation: Rewrite the equation in standard quadratic form by adding 8x8x to both sides.\newlineEquation: x2+8x12=0-x^2 + 8x - 12 = 0
  2. Use Quadratic Formula: Since the quadratic equation is not easily factorable, we will use the quadratic formula to find the solutions for xx. The quadratic formula is x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}, where a=1a = -1, b=8b = 8, and c=12c = -12.
  3. Calculate Discriminant: Calculate the discriminant b24acb^2 - 4ac to determine the nature of the roots.\newlineDiscriminant: 824(1)(12)=6448=168^2 - 4(-1)(-12) = 64 - 48 = 16
  4. Apply Quadratic Formula: Since the discriminant is positive, we have two real and distinct solutions. Now, apply the quadratic formula.\newlinex=8±162×1x = \frac{-8 \pm \sqrt{16}}{2 \times -1}
  5. Simplify Solutions: Simplify the solutions. x=8±42x = \frac{{-8 \pm 4}}{{-2}}
  6. Solve for x Values: Solve for both possible values of x.\newlineFirst solution: x=(8+4)/2=4/2=2x = (-8 + 4) / -2 = -4 / -2 = 2\newlineSecond solution: x=(84)/2=12/2=6x = (-8 - 4) / -2 = -12 / -2 = 6
  7. Final Solutions: Write the solutions in ascending order, separated by a comma.\newlineFinal solutions: 2,62, 6
