Basic concept of quadratic equation part 3

Let See the basic concept of quadratic equation part 3.

Finishing the square methodology is among the strategies to seek out the roots of the given quadratic equation. A polynomial equation with a degree equal to 2 is called a quadratic equation. ‘Quad’ means 4 however ‘Quadratic’ means ‘to make square’. A quadratic equation in its normal type is represented as:

ax^2 + bx + c = 0, the place a,b and c are actual numbers such {that a} ≠ Zero and x is a variable.

To seek out the roots of a quadratic equation within the type:

ax^2+bx+c=0

observe these steps:

(i) If a doesn't equal 1, divide both sides by an (in order that the coefficient of the x^2 is 1.

(ii) Rewrite the equation with the fixed time period on the precise facet.

(iii) Full the square by including the sq. of one-half of the coefficient of x to either side.

(iv) Write the left facet as a square and simplify the precise facet.

(v) Equate and clear up.

To solve a quadratic equation by changing the form of the equation so that the left side is a perfect square by completing the square method:

Must watch my youtube video here will get a unique trick to solve the quadratic equation through Completing Square Method.
