Hello oddworld7836!
Factor the expression into an equivalent form 12y² - 75.
By observing the expression, we can see that, 3 is the only common factor in both the terms of the expression. So, take the common factor 3 out.
Now, look at (4y² - 25). They don't have any common factors but they appear in the form of the algebraic identity ⇨ a² - b² = (a + b) (a - b). Here,
- a² = 4, a = 2 (√a² = ✓4 = 2)
- b² = 25, b = 5 (√b² = ✓25 = 5)
So, the (4y² + 25) becomes...
Now, bring the 3 (common factor) & rewrite the complete expression.
We can't further simplify it. Also, remember that the simplified form of an expression is equivalent to the expression. So, 3 (2y - 5) (2y + 5) is equivalent to 12y² - 75.

The workdone by the tension is; Positive
<h3>What is Tension force?</h3>
This question is from an elevator that is held by a single cable which is ascending but slowing down.
Now, this elevator is being acted upon by two vertical forces known as Tension which is upwards and the weight of the elevator acting downwards.
However, the direction of motion of the elevator is in the same direction as the tension in the cable. Thus, we can say that the work done by tension is positive.

Answer:
Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1
Explanation:
Thus, Electronegativity difference in Cl2 = 3.2 -3.2 = 0
Electronegativity difference in NaCl = 3.2-0.9 = 2.3
Similarly, Electronegativity difference in HCl = 3.2 - 2.1 = 1.1
Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl2
