How to Determine Nature of Roots -- Quadratic Equations

Investigating the nature of roots Use the quadratic formula to determine the roots of the quadratic equations given below and take special note of: the the expression under the square root sign and the type of number for the final answer (rational/irrational/real/imaginary) x2 ? 6x + 9 = 0 x2 ?. Solution: The given quadratic equation is in the general form. ax 2 + bx + c = 0. Then, we have a = 1, b = and c = Find the value of the discriminant b 2 - 4ac. b 2 - 4ac = () 2 - 4 (1) (64) b 2 - 4ac = - b 2 - 4ac = 0. So, the roots are real, equal and rational. Nature of the Roots. Points where the graph cuts the x-axis are called the roots. Discriminant b? – 4ac is used to find the nature of the roots. Discriminant is NOT given in the N5 Maths exam – please memorise. Trinomial coefficients a, b & c (from ax? + bx + c) are substituted into b? – 4ac.

You will learn about the nature of roots of quadratic equation using the discriminant formula, quadratic formula, roots of a cubic equation, real roots, unreal roots, irrational roots, imaginary roots and other interesting facts around the topic. You can also check out the playful calculators to know more about the lesson and try your hand at solving a few interesting practice questions at the end of the page. The word " Quadratic " is derived from the word " Quad " which means square.

Now, to find the nature of the roots of the quadratic equation, we will first calculate the roots of the equation. Nature of roots specifies that the equation has real roots, irrational roots, or imaginary roots. Here is the quadratic formula used to find the roots of a quadratic equation. This is called a " discriminant " because it discriminates the roots of the quadratic equation based on its sign. This means that the quadratic equation has two real and distinct roots.
