Step-by-step explanation:
The point that lies on the perpendicular bisector of AB is point N
<h3>How to determine the point?</h3>
The circle is given as:
Circle N
The chord is given as:
Chord AB
The perpendicular bisector of the chord is any line drawn from the center of the circle that divides the chord in equal halves.
This means that the point starts from point N
Hence, the point that lies on the perpendicular bisector of AB is point N

Answer:
(d) (4x² +7)(x -3)
Step-by-step explanation:
This polynomial can be factored by factoring pairs of terms.
= (4x³ -12x²) +(7x -21)
= 4x²(x -3) +7(x -3)
= (4x² +7)(x -3)

<em>Additional comment</em>
The answer choices suggest we're not interested in irrational or complex factors. The quadratic (4x² +7) could be factored into linear terms involving irrational complex numbers. The form for "difference of squares" would be used for the purpose.
