n distinct real zeroes. The zero of the polynomial p(x) satisfies the equation p(x) = 0. For any linear polynomial ax + b‚ zero of the polynomial will be given by the expression (-b/a). 5. The number of real zeros of the polynomial is the number of times its graph touches or intersects x axis. 6. 7. 8. 9. 10. A polynomial p(x) of degree n will have atmost n real zeroes A linear polynomial has atmost one real zero. A quadratic polynomial has atmost two real zeroes. A cubic polynomial has atmost three

When you are graphing quadratics‚ it is the same as graphing linear equations but‚ quadratics have the curvy line‚ called a parabola. When you are graphing your points‚ it is best to graph three or more points. You are really going to need to point three or more points‚ because if there are less than three you will not have a correct graph‚ graphing more than three will insure that your graph will be correct. The biggest number that they say you have to graph will most likely not be able to be graphed

Introduction The aim of this investigation is to identify the nature of the roots of quadratics and cubic functions. Part One Case One For Case One‚ the discriminant of the quadratic will always be equal to zero. This will result in the parabola cutting the axis once‚ or twice in the same place‚ creating a distinct root or two of the same root. For PROOF 1‚ the equation y=a(x-b)2 is used. PROOF 1 y = 3 (x – 2)2 = y = 3 (x2 – 4x + 4) = y = 3x2 – 12x + 12 ^ = b2 – 4ac = (-12)2 – 4 x 3 x

Jaquavia Jacques Ms. Cordell 1st period December 9‚ 2014 Quadratics is used to help to determine what is on a graph. There are many formulas that are used to put points on a graph to create parabolas. Parabolas are “U” shaped figures on a graph. Parabolas are examples of quadratics on a graph. Parabolas can be positioned up or down‚ which means if the arrows are going up it has a minimum point‚ and if the arrows are going down that means it has a maximum point. When graphing using the vertex formula:

Quadratic functions are used all the time‚ every day‚ all over the world. Even though right now‚ it doesn’t seem like this kind of math is ever going to creep back into our life. That is actually far from true. These math skill are crucial to have if one ever decides to do anything in engineering‚ or something like that. Those types of jobs are now becoming more and more popular‚ because the world is always going to need educated people who know how to construct or refurbish buildings and homes.

Pythagorean Quadratic Member MAT 222 Introduction to Algebra Instructor Yvette Gonzalez-Smith August 04‚ 2013 Pythagorean Quadratic The Pythagorean Theorem is an equation that allows a person to find the length of a side of a right triangle‚ as long as the length of the other two sides is known. The theorem basically relates the lengths of three sides of any right triangle. The theorem states that the square of the hypotenuse is the sum of the squares of the legs

order to find the vertex of the quadratic equation‚ begin by using the proper formula - b / 2(a) to find it. In the equation there is an (a) (b) (c) which is needed for the vertex equation. First look at the equation and determine what are the values of the three variable. In this case (a)= 2‚ (b)= 8‚ (c)= 5. Now plug them in properly into the vertex equation. * Notice in the vertex equation there is a negative sign!!! DO NOT FORGET! When plugged into the equation‚ it should state -8 / 2(2). Now
