Infinitely many
Answer:
zero
Step-by-step explanation:
(x^2+3)(4x−5)
5x^2(x+4)(3x−5)
5x(x^2+3)(4x−5)
5x(x^2−3)(4x+5)
The expression correctly shows 20x⁴-25x³+60x²-75x will be 5x(x²+3)(4x-5).Option C is correct.
An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,
The expression is,
=20x⁴-25x³+60x²-75x
Take 5x³ from the first two terms and 15x from the third and fourth terms as
=20x⁴-25x³+60x²-75x
=5x³(4x-5) + 15x(4x-5)
=(5x³+15x)(4x-5)
Thus, the expression correctly shows 20x⁴-25x³+60x²-75x will be 5x(x²+3)(4x-5). Option C is correct.

Step-by-step explanation:
The third option: 5x(x^2+3)(4x-5)
because FOIL first, inner, outter, last
The two parentheses become (4x^3-5x^2+12x)
then 5x outside multiplys that whole parentheses. To get your correct expression
