Complete the steps of the derivation of the quadratic formula. step 2: step 3: step 4: step 5:

To complete the derivation of the quadratic equation:

Given:

Add both sides we have;

Taking square root both sides we have;

⇒

⇒

Subtract from both sides we have;

Therefore, complete derivation for the quadratic equation is:

Step 1.

Step 2.

Step 3.

Step 4.

Step 5.

or

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
