Answer:
A
Step-by-step explanation:
In this question, we are concerned with selecting which of the options best represents the difference of two squares.
Let’s have an exposition below as follows;
Consider two numbers, which are perfect squares and can be expressed as a square of their square roots;
a^2 and b^2
where a and b represents the square roots of the numbers respectively.
Inserting a difference between the two, we have;
a^2 - b^2
Now by applying the difference of two squares, these numbers will become;
a^2 - b^2 = (a + b)(a-b)
So our answer out of the options will be that option that could be expressed as above.
The correct answer to this is option A
Kindly note that;
x^2 -9 can be expressed as x^2 - 3^2 and consequently, this can be written as;
(x-3)(x + 3)

Answer:
f(x) = 3(x+2)(x-2)
Step-by-step explanation:
We are given the following the quadratic function and we are to rewrite it in intercept or factored form:
We can factorize the given function so taking the common factors out of it to get:
The term is in the form
so it can further be factorized to give:
Therefore, the factored form of the given quadratic function is f(x) = 3(x+2)(x-2).
Answer:
3(x-2)(x+2)
Step-by-step explanation:
Given equation is :
f(x) = 3x²-12
We have to rewrite the given function in factored or intercept form.
Since, we know that 3 and 12 are multiples of 3.
taking 3 as common , we get
f(x) = 3(x²-4)
using differernce formula in above equation , we get
a²-b² = (a-b)(a+b)
f(x) = 3(x-2)(x+2)
Hence, the given factors are 3,(x-2) and (x+2).

The linear equation 24x-6y=18 can be rewritten in slope-intecept form as y=4x-3. The slope of the graph is 4 and the y-intercept is -3. To graph, begin at the y-intercept and use the slope to locate the next point, then draw a line through these points.
The equation the student wants to graph is 24x-6y=18. To plot this equation, start by solving for y to put this equation in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
To do this, subtract 24x from both sides to get -6y = -24x + 18. Then, divide every term by -6 to yield y=4x-3. So, the slope (m) of the line is 4 and the y-intercept (b) is -3.
Begin graphing by plotting the y-intercept (0,-3) on the graph. From there, use the slope to find your next point by going up 4 units and right 1 unit. Draw a line through these points, and you have your graph.
