Correct Answer:
A. (x−2)(x+3)=0
To find the quadratic equation from its roots, we use the principle that if 'a' and 'b' are the roots, then the equation can be written as (x - a)(x - b) = 0. Given the roots are 2 and -3, we substitute these values into the formula.
- For the root 2, the factor is (x - 2).
- For the root -3, the factor is (x - (-3)), which simplifies to (x + 3).
Therefore, the correct equation is (x - 2)(x + 3) = 0, making option A accurate. The other options would yield different roots:
- Option B, (x - 3)(x - 4) = 0, has roots 3 and 4.
- Option C, (x + 2)(x + 3) = 0, has roots -2 and -3.
- Option D, (x - 2)(x - 3) = 0, has roots 2 and 3.
