(4x)^2=4x times 4x
4x^2=4 times x times x=4(x^2)
(4x)^2=16x^2
4x^2=4(x^2)
values are not equal
(just for fun: 4x^2=(2x)^2)
Answer:
A = 6k(k + 6)
Step-by-step explanation:
We have to solve the given equation for the value of A,
(6k² - 36k)(k² + 12k + 36) = A(k² -36)
6k(k - 6)(k + 6)² = A(k - 6)(k + 6)
A = 
A = 6k(k + 6)
Therefore, value of A is 6k(k + 6).
Answer:

The coordinates of the vertex are (1.5, 1.75) and the axis of symmetry is at x = 1.5.
We can find the vertex by using the formula for finding x-coordinates. The formula for the x-coordinate of a vertex is below.
-b/2a
In this equation, a is the coefficient of the x^2 term (1) and b is the coefficient of the x term (-3). Then we can plug in to find the x term.
-(-3)/2(1)
3/2
1.5
Now that we have this term, we can plug it in for all values of x to find the y term.
x^2 - 3x + 4
1.5^2 - 3(1.5) + 4
2.25 - 4.5 + 4
1.75
Now we know that the vertex is at (1.5, 1.75). Now finding the axis of symmetry is easy because the axis of symmetry in any quadratic is simply x = [x-coordinate of vertex]. So in this case it would be x = 1.5.
