Math Problem Statement

Diketahui p dan q adalah akar-akar dari 2x^2 - 2x - 24, berapa p dan q itu?

Solution

The problem states that pp and qq are the roots of the quadratic equation:

2x22x24=02x^2 - 2x - 24 = 0

We can solve for pp and qq using the quadratic formula:

x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

For the given equation, 2x22x24=02x^2 - 2x - 24 = 0, we have:

  • a=2a = 2
  • b=2b = -2
  • c=24c = -24

Let's solve this equation using the quadratic formula.The roots of the quadratic equation 2x22x24=02x^2 - 2x - 24 = 0 are:

p=4andq=3p = 4 \quad \text{and} \quad q = -3

Let me know if you need further details or explanations!

Here are 5 related questions for further practice:

  1. How do you factorize the equation 2x22x24=02x^2 - 2x - 24 = 0?
  2. What are the sum and product of the roots of this quadratic equation?
  3. How would you solve this equation by completing the square?
  4. What happens to the roots if we change the coefficient of x2x^2?
