what is a real root Real roots The real roots are expressed as real numbers Suppose a x 2 b x c 0 is a quadratic equation and D b 2 4 a c is the discriminant of the equation such that If D 0 then the roots of the equation are real and equal
Every positive real number has two square roots one positive and one negative For this reason we use the radical sign to denote the principal nonnegative square root 2 and a negative sign in front of the radical to denote the negative square root An imaginary root cannot be a real root but is also a special kind of complex number where the real part of the complex number is 0 Similar to how a real number is a complex number where the imaginary part is 0 A non real root is a root that is not real It is a complex root it can be an imaginary root but its real part can be non zero

A real root is a solution to an equation that is also a real number Real roots of a polynomial equation are solutions that belong to the set of real numbers In the context of quadratic equations like ax2 bx c 0 real roots can be found using the quadratic formula x b b2 4ac 2a For example consider the equation x2 4 0 About Transcript The Fundamental Theorem of Algebra can be used in order to determine how many real roots a given polynomial has Check it out Created by Sal Khan Questions Tips Thanks Want to join the conversation Sort by Top Voted Hannah Kim 10 years ago Can t the number of real roots of a polynomial p x that has degree 8 be 7
Lesson Explainer Real and Complex Roots of Polynomials Mathematics Start Practising In this explainer we will learn how to understand the relationships between the degree of a polynomial its coefficients and its roots and how to apply this knowledge to solve problems We begin by considering two important theorems regarding polynomials A polynomial equation whose degree is 2 is known as quadratic equation A quadratic equation in its standard form is represented as ax2 bx c 0 where a b and c are real numbers such that a 0 and x is a variable The number of roots of a polynomial equation is equal to its degree So a quadratic equation has two roots
