Assuming an equation with one side as a squared variable expression and the other side as a numeric expression, which of the following statements is correct?

Statement #1:If the numeric expression is zero, there are two solutions.

Statement #2: If the numeric expression is zero, there is one solution.

Statement #3: If the numeric expression is zero, there are no solutions.

1 answer

Let's examine the implications of the equation in question, which has a squared variable expression on one side and a numeric expression (assumed to be zero for analysis) on the other side.

Assuming the equation takes the form \( ax^2 + bx + c = 0 \):

  1. If we rewrite this as \( x^2 = 0 \), the expression on the left side is a squared term.

  2. When the numeric expression is zero, we have \( x^2 = 0 \).

Now, let's analyze what happens:

  • The equation \( x^2 = 0 \) can be solved by taking the square root of both sides, yielding \( x = 0 \).
  • This means that there is exactly one solution: \( x = 0 \).

Based on this analysis:

  • Statement #1: "If the numeric expression is zero, there are two solutions." (Incorrect).
  • Statement #2: "If the numeric expression is zero, there is one solution." (Correct).
  • Statement #3: "If the numeric expression is zero, there are no solutions." (Incorrect).

Thus, the correct statement is Statement #2. If the numeric expression is zero, there is one solution.
