Which Quadratic Equation is Equivalent to x² + 5x + 6 = 0?

The quadratic equation equivalent to the expression x² + 5x + 6 = 0 can be determined by examining its components.

To start, let’s rewrite the equation in standard form:

x² + 5x + 6 = 0

This equation is already in the standard quadratic format of ax² + bx + c = 0, where:

  • a = 1
  • b = 5
  • c = 6

Next, we can factor the quadratic equation to see if it simplifies further. We are looking for two numbers that multiply to give c (6) and add up to b (5). The numbers 2 and 3 meet this criteria:

(x + 2)(x + 3) = 0

Thus, the quadratic equation can also be expressed as:

(x + 2)(x + 3) = 0

To summarize, the equivalent quadratic equation to x² + 5x + 6 = 0 is:

(x + 2)(x + 3) = 0

This means that the roots of the equation are x = -2 and x = -3.
