Explain how to find the values of a, b, and c, in a quadratic equation?

Given:

A quadratic equation with values (coefficients) as a, b and c

To Find:

Values of a, b and c

Solution:

Let the standard form of a quadratic equation be  where  and  are constants and ,  and  is called variable.

Example -

(i) Let  be quadratic equation. Compare this equation with standard form and we can deduce that

(ii) Let  be another quadratic equation. Here,  because, the value is 0 for variable .

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.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
