Math Problem Statement

find a quadratic the sum anf product of whose zeroes are -3 and 2, respectively

Solution

To find a quadratic equation where the sum and product of the roots are given, we can use the general form of a quadratic equation based on its roots:

x2(sum of roots)x+(product of roots)=0x^2 - (\text{sum of roots})x + (\text{product of roots}) = 0

In this case:

  • The sum of the roots is 3-3.
  • The product of the roots is 22.

Substituting these values into the equation:

x2(3)x+2=0x^2 - (-3)x + 2 = 0

This simplifies to:

x2+3x+2=0x^2 + 3x + 2 = 0

Thus, the quadratic equation with a sum of roots 3-3 and a product of roots 22 is:

x2+3x+2=0x^2 + 3x + 2 = 0

Would you like a breakdown of how to factor this equation or further details?

Here are five related questions for further exploration:

  1. What are the actual roots of the equation x2+3x+2=0x^2 + 3x + 2 = 0?
  2. How can we verify the sum and product of the roots of x2+3x+2=0x^2 + 3x + 2 = 0?
  3. How would the equation change if the sum and product of the roots were different values?
  4. Can you find a quadratic equation with roots that have a sum of 4 and a product of 5-5?
  5. How does the quadratic formula confirm the roots for x2+3x+2=0x^2 + 3x + 2 = 0?

Tip: Remember that if you know the sum and product of the roots, you can always construct a quadratic equation in the form x2(sum of roots)x+(product of roots)=0x^2 - (\text{sum of roots})x + (\text{product of roots}) = 0.
