Answer:

How do you find the sum of factors of a quadratic equation?

Let r and s be the factors for the quadratic equation such that x^2+Bx+C=(x−r)(x−s) where sum of factors (r+s)=−B and the product of factors rs = C r = -2 - u s = -2 + u Two numbers r and s sum up to -4 exactly when the average of the two numbers is \frac{1}{2}*-4 = -2.

How do you solve a quadratic equation?

Quadratic equations such as this one can be solved by completing the square. In order to complete the square, the equation must first be in the form x^{2}+bx=c.

Draw your own rectangle, with an area of 24 square units, on the coordinate plane. Then, identify the vertices of your rectangle

Gnoma [55]

Answer:

First you should remember that the formula for calculating area of a rectangle is;

Area=Length × width

You can decide to have a rectangle with different dimensions provided the area is 24 square unit

For this case, lets choose a rectangle with vertices at (1,0), (7,0),(1,4), (7,4)

After plotting these coordinates, you will notice your rectangle has a length of 6 units and a width of 4 units

A single unit is 1 square unit.When you Count the number of units inside the rectangle formed you realize you have 24 units covered inside

The area of the 24 units will be;
