Description

"Formula Method" Quadratic Equation of One Variable PPT Courseware

Use the combination method to solve the quadratic equation of one variable 2x²+4x+1=0

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

1. Convert the original equation into the form x²+px+q=0.

2. Move items and organize to get x²+px=-q

3. Add half the square of the linear coefficient p to both sides of the equation x²+px= -q.

General steps for solving quadratic equations of one variable using the formula method:

1. Put the equation into a general form. And write the values ​​of a, b, c.

2. Find the value of b²-4ac.

3. Substitute the root formula:

4. Write the solution to the equation: x1=?, x2=?

Thought questions:

1. The quadratic equation of x with respect to x is ax²+bx+c=0 (a≠0). When a, b, c satisfy what conditions, the two roots of the equation are opposite to each other?

2. When m takes any value, the equation x²+(2m+1)x+m²-4=0 has two equal real number solutions.
