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.

Pythagorean Theorem because it is a right triangle.
The formula that represents l in terms of f and w is l = (f-5w)/2
<h3>Subject of formula </h3>
This is way of representing a variable with other variables in an expression, Given the expression that represent the amount of fence a farmer needs to create a garden with width w and length
f = 5w + 2l
Make l the subject of the formula
2l = f - 5w
Divide both sides by 2
2l/2 = (f-5w)/2
l = (f-5w)/2
Hence the formula that represents l in terms of f and w is l = (f-5w)/2
