Which model represents the factors of 4x^2-9

Mathematics

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).

You are building an entertainment center for a television. You need to
Rainbow [258]
This question is about Pythagorean theorem, a square + b square = c square
Where a and b represents either leg of the triangle (width or height), and c represents the hypotenuse (the diagonal)
Let height = h
For the question above, the equation will be
36 square + h square = 45 square
Subtract 36 square from both sides
36 square - 36 square + h square= 45 square - 36 square
h square = 2025 - 1296
h square = 729
Find the square root of both sides
Square root of h square = square root of 729
h = 27
The height of the television is 27

What is the simplified form of (4j2+6)+(2j2-3)
Galina-37 [17]

Answer: 6j^2+3

Step-by-step explanation:

In order to solve this exercise it is important to remember the multiplication of signs. Notice that:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

In this case you have the following expression given in the exercise:

(4j^2+6)+(2j^2-3)

Where the variable is "j".

When you multiply signs, you get:

=4j^2+6+2j^2-3

Now you need to identify that like terms and then you need to add them (or combine them). So, applying this procedure you get that the simplified form of the expression is  the shown below:

=6j^2+3

As you can observe, you get a 2nd degree binomial.
