As we saw before the standard form of a quadratic equation is.
What is a root in math quadratic equation.
The name comes from quad meaning square as the variable is squared in other words x 2.
To examine the roots of a quadratic equation let us consider the general form a quadratic equation.
This is an easy method that anyone can use.
Ax 2 bx c 0 here a b and c are real and rational numbers to know the nature of the roots of a quadratic equation we will be using the discriminant b 2 4ac.
We can help you solve an equation of the form ax 2 bx c 0 just enter the values of a b and c below.
This formulas give both roots.
Because b 2 4ac discriminates the nature of the roots.
If the discriminant is positive.
Only if it can be put in the form ax 2 bx c 0 and a is not zero.
The solutions called roots.
Play with the quadratic equation explorer so you can see.
Well the quadratic equation is all about finding the roots and the roots are basically the values of the variable x and y as the case may be.
B sqrt b 2 4ac 2a and b sqrt b 2 4ac 2a.
It is just a formula you can fill in that gives you roots.
Write the quadratic equation given the following roots.
These are all quadratic equations in disguise.
Solution to problem 4.
Another way to find the roots of a quadratic function.
Further the equation have the exponent in the form of a b c which have their specific given values to be put into the equation.
4 and 2 show answer there are a few ways to approach this kind of problem you could create two binomials x 4 and x 2 and multiply them.
The quadratic formula gives that the roots of this equation are 2 and 4 and both of these are real so the equation has two real roots.
Consider the quadratic equation a real number x will be called a solution or a root if it satisfies the equation meaning it is easy to see that the roots are exactly the x intercepts of the quadratic function that is the intersection between the graph of the quadratic function with the x axis.
