Key Strategy in Solving Quadratic Equations using the Square Root Method. The general approach is to collect all {x^2} terms on one side of the equation while keeping the constants to the opposite side. After doing so, the next obvious step is to take the square roots of both sides to solve for the value of x.

Solved examples to form the quadratic equation whose roots are given According to the problem, coefficients of the required quadratic equation are real and its one root is -2 + i. We know in a quadratic with real coefficients imaginary roots occur in conjugate pairs).

Quadratic Equations When solving a quadratic equation of the form ax2 -+- c O by taking square roots, you may need to use the following properties of square roots to simplify the solutions. (In a later lesson, these properties are stated in a general form and then proved.) more Symbols and b 0 where a 0 and b > O Numbers Property Name

To solve the quadratic equation by Using Quadratic formula: Step I: Write the Quadratic Equation in Standard form. Step II: By comparing this equation with standard form ax. 2 + b x + c = 0 . to identify the values of a , b , c. Step III: Putting these values of a, b, c in Quadratic formula . and solve for x. Example 5:

A quadratic equation is an equation of the form ax2 + bx + c = 0, where a≠ 0, and a, b, and c are real numbers. Solving Quadratic Equations by Factoring We can often factor a quadratic equation into the product of two binomials. We are then left with an equation of the form (x + d) (x + e) = 0, where d and e are integers.

x - 4 = 10 Solution. 2 x - 4 = 10 Solution. 5x - 6 = 3 x - 8 Solution. Solution. Solution. 2 (3 x - 7) + 4 (3 x + 2) = 6 (5 x + 9 ) + 3 Solution. Solution. EQUATIONS CONTAINING RADICAL (S) - Solve for x in the following equations. Solution. For a quadratic equation ax2+ bx + c = 0, a 0, if (i) D = b2. 4ac > 0, the equation has two real distinct roots, which are 2a b + b2 4ac and 2a b b2 4a c . (ii) D = b2. 4ac = 0, then equation has two real equal roots, each equal to 2a b (iii) D = b2. Write the equation with only the square root on the left hand side Use the additive inverse to get all other terms on the right hand side and only the square root on the left hand side. \[\sqrt{p-2} = 3\]
