To solve the quadratic equation \( (x + 3)(x + 4) = 0 \) using the zero product property, we first set each factor equal to zero:
- \( x + 3 = 0 \)
- \( x + 4 = 0 \)
Now we can solve each equation:
-
For \( x + 3 = 0 \): \[ x = -3 \]
-
For \( x + 4 = 0 \): \[ x = -4 \]
So the solutions to the equation \( (x + 3)(x + 4) = 0 \) are \( x = -3 \) and \( x = -4 \).
Regarding Oliver's work, if he wrote \( x - 3 = 0 \) in the second row instead of \( x + 3 = 0 \), then he made a mistake in identifying the factors of the equation. Hence, his work would not be accurate.
To summarize:
- Yes, the correct factor to set equal to zero is \( x + 3 = 0 \), not \( x - 3 = 0 \).
- Oliver's conclusion based on that mistake would not be accurate.
So to answer your question about whether Oliver's work is accurate: No, it is not accurate.
