Quadratic Equation: x^2 - 8x - 20 = 0

To solve the quadratic equation x^2 - 8x - 20 = 0 using the cutting and pasting method, you need to follow these steps:

Step 1: Splitting the Middle Term
- The middle term of the equation is -8x.
- We need to find two numbers whose product is equal to the product of the coefficient of x^2 (which is 1) and the constant term (which is -20).
- The product of 1 and -20 is -20.
- We need to find two numbers whose sum is equal to -8 (the coefficient of x).
- After considering various possibilities, let's choose -10 and 2.
- So, we can split -8x as -10x + 2x.

Step 2: Rearranging the Terms
- Rearrange the equation by splitting the middle term:
x^2 - 10x + 2x - 20 = 0

Step 3: Grouping the Terms
- Group the terms in pairs:
(x^2 - 10x) + (2x - 20) = 0

Step 4: Taking Out Common Factors
- Take out the common factors from each group:
x(x - 10) + 2(x - 10) = 0

Step 5: Combining Like Terms
- Combine the like terms:
(x + 2)(x - 10) = 0

Step 6: Setting each Factor to Zero
- Set each factor to zero and solve for x:
x + 2 = 0 or x - 10 = 0

Step 7: Solving for x
- Solve the equations:
x = -2 or x = 10

Step 8: Final Solution
- The solutions to the quadratic equation x^2 - 8x - 20 = 0 are x = -2 and x = 10.
