Question:medium
Let \( x=2 \) be a root of \( y = 4x^2 - 14x + q = 0 \). Then \( y \) is equal to:
Let \( x=2 \) be a root of \( y = 4x^2 - 14x + q = 0 \). Then \( y \) is equal to:
Show Hint
Once you know \( q=12 \), you can quickly check the options by looking at the constant term. In Option (A), \( (-2) \times (-6) = +12 \). This matches our value of \( q \).

- \( (x - 2)(4x - 6) \)
- \( (x - 2)(4x + 6) \)
- \( (x - 2)(-4x - 6) \)
- \( (x - 2)(-4x + 6) \)
- \( (x - 2)(4x + 3) \)
Show Solution
The Correct Option is A
