What pattern is represented by the polynomial ?
Ymorist [56]

Answer:

choice C. Perfect square trinomial is correct.

Step-by-step explanation:

We need to find the pattern which is represented by the polynomial 4x^2+12x+9.

To find that pattern, we need to factor 4x^2+12x+9

4x^2+12x+9

=4x^2+6x+6x+9

=2x(2x+3)+3(2x+3)

=(2x+3)(2x+3)

=(2x+3)^2

which is a perfect square.

Hence choice C. Perfect square trinomial is correct.

Juan wants to change the shape of his vegetable garden from a square to a rectangle, but keep the same area so he can grow the s
sergeinik [125]

The quadratic equation that would model this scenario is

x^{2} = 2x(x-16)

Let us take the side of the square = x

Area of the square = x²

Length of the rectangular garden = 2x

Width of the rectangular garden = x-16

So, the area of the new vegetable garden = length*width

Area of the new or rectangular vegetable garden = 2x(x-16)

<h3>What is a quadratic equation?</h3>

The polynomial equation whose highest degree is two is called a quadratic equation. The equation is given by ax^2+bx+ccoefficient x^{2}non-zero.

Since it is given that

Area of square garden = area of the rectangular garden

x^{2} = 2x(x-16)

Thus, the quadratic equation that would model this scenario is

x^{2} = 2x(x-16)
