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.

Step-by-step explanation:

Brownies

simply multiply the 18 by 3 we get 54 and if we multiply 54 by 5 we get 270.

we multiply it by 5 because in series it skip 1 number to multiply next.

Cooldies

first we multiply 16 by 2 we get 32.

next we multiply 32 by 3 we get 96.

and next we multiply 96 by 4 we get 384.

Simply increment in multiplication.
