To determine if Oliver's work is accurate, let's analyze the given quadratic equation (x+3)(x+4)=0.
Using the Zero Product Property, we set each factor equal to zero:
- \( x+3=0 \)
- \( x+4=0 \)
From these equations, we can solve for \( x \):
- \( x+3=0 \) gives us \( x=-3 \)
- \( x+4=0 \) gives us \( x=-4 \)
Next, we should look at the other line in the table provided:
- \( x−3=0 \) is not part of the original factors and is incorrect.
- The values \( x=3 \) and \( x=-4 \) do not match the solutions we found.
Therefore, Oliver's work includes an incorrect equation \( x−3=0 \) which should not be there. The factor should have been \( x+3=0 \).
Based on this analysis, the correct response regarding the accuracy of Oliver's work is:
No, x−3=0 in the second row should be x+3=0.
