"Association Method" Quadratic Equation of One Variable PPT Courseware 2

Description

"Association Method" Quadratic Equation of One Variable PPT Courseware 2

We obtain the roots of quadratic equations by arranging them into perfect squares. This method of solving quadratic equations is called the arranging method.

Steps to solve quadratic equations of one variable using the formula method:

1. Move the term: Move the constant term to the right side of the equation;

2. Formula: Add the square of half the absolute value of the linear term coefficient to both sides of the equation;

3. Deformation: factorize the left side of the equation and combine similar factors on the right side;

4. Square root: According to the meaning of square root, the square root of both sides of the equation;

5. Solve: Solve linear equations of one variable;

6. Definite solution: Write the solution of the original equation.

Write each of the following equations in the form (x+m)²=n

(1)x²－2x+1=0

(2)x²+8x+4=0

(3)x²－x+6=0

Multiply or divide both sides of the following equation by the appropriate number, and then write it in the form (x+m)²=n

(2)2x²+3x－2=0

(2)x²+x－2=0
