QUADRATIC EQUATIONS PDF
Introduction. This unit is about how to solve quadratic equations. A quadratic equation is one which must contain a term involving x2, e.g. 3x2, −5x2 or just x2 on. Roots of a quadratic equation: A real number α is said to be a root of the The roots of the quadratic equation ax2 + bx + c = 0 are the same as the zeroes. Equation: An equation is a statement of equality „=‟ between two expression for particular values of the variable. For example. 5x + 6 = 2, x is the variable.

We will also find cube roots of unity and use these in solving problems. Same method can be applied while solving quadratic equation by factorization.
Solve each of the following quadratic equations by factorization method: Example 2. Algebra Solution: For real and equal roots, discriminant is equal to zero.
Solve each of the following quadratic equation by quadratic formula: These relationships helps to find out a quadratic equation when two roots are given. Notes Example 2.
From the above examples , we can make the following conclusions: Is it always true that complex roots occur in conjugate pairs? Step 2. Translating the word problem into Mathematics form symbolic form according to the given condition.
