If using the method of completing the square to solve the quadratic equation

Mathematics
1 answer:
shtirl [24]4 years ago

Answer:

1

Step-by-step explanation:

To complete the square, first you must make sure that the coefficient of the x^2 term is 1. Here you have x^2 - 2x - 36 = 0. Since the x^2 term is simply x^2, you do have a coefficient of 1 for the x^2 term.

To find the number you need to add to complete the square, take the coefficient of the x term. Divide it by 2. Then square it.

The x term is -2x. The coefficient of the x term is -2.

Take half of -2 which is -1.

Now square -1 to get 1.

You need to add 1 to complete the square.

Pick’s Theorem is used to find the areas of figures on lattices easily. The formula is:

A = (B)/2 + I - 1, where B is the number of points on the border of the shape, and I is the number of points inside the shape.

Here, there are 8 points on the outside of the shape, and there are 12 points inside the shape. So, we do:

8/2 + 12 - 1 = 4 + 12 - 1 = 15 units squared.

We can check by finding the areas of the non-shaded region and subtracting that area from the whole rectangle area of 4 * 10 = 40:

4 * 1 + (3 * 1)/2 + 1 * 9 + (3 * 1)/2 + (9 * 2)/2 = 25

40 - 25 = 15, so we’re right!

The answer is 15 units squared, or choice (B).
