The model (x+a)(x-a) will represents the factors of 4x²-9 as (2x+3)(2x-3).
<h3>What are the quadratic equations in one variable completing the squares method?</h3>
The "completing the squares" method aims to construct a quadratic equation of the form where the x variable is entirely covered by a single squared term, which is the square of a linear expression in x, as the name suggests.
The quadratic equation can resemble this:
x²-a² = (x+a)(x-a)
Given equation;
⇒4x²-9
⇒(2x)²-3²
The equation can be modeled as;
(2x+3)(2x-3)
Hence the model (x+a)(x-b) will represents the factors of 4x²-9 as (2x+3)(2x-3).

The equation is 2x +3.00. If you want to find the cost for two minutes, plug two in for x. Then it will become 4 + 3.00. Add those together and you will get 7.00. So all you have to do is replace x for the number of minutes, then multiply it by two, and finally add it to 3.00
Answer:
253 feet
Explanation:
Subtract 125ft. from 378ft.
Answer:
1728
Step-by-step explanation:
We can write the expression as:
= ![12^{2X(3/2)}](https://tex.z-dn.net/?f=12%5E%7B2X%283%2F2%29%7D)
So,
=
.
Which is 1728.
