learning target

1. Understand the concept of quadratic equation of one variable and determine the coefficients according to the general formula of the quadratic equation of one variable.

2. Flexibly apply the concept of quadratic equations to solve related problems

3. Understand the concept of solutions to quadratic equations of one variable and be able to solve related problems

Put the following equations into general form, and indicate their quadratic terms, linear terms, constant terms and their coefficients respectively:

3x(x-1)=5(x+2)

(1) The general form of a quadratic equation is not unique, but it is customary to convert the coefficients of the quadratic terms into positive integers.

(2) The quadratic terms, quadratic term coefficients, linear terms, linear term coefficients, constant terms, etc. of a quadratic equation are all for general forms.

(3) When pointing out the coefficients of a quadratic equation, do not miss the previous symbols

1. The concept of quadratic equation of one variable

An integral equation that contains only one unknown and the highest degree of the unknown is 2 is called a quadratic equation.

2. General form of quadratic equation of one variable

In general, any quadratic equation with respect to x can be

Transformed into the form of ax²+bx+c=0, we call ax²+bx+c=0 (a, b, c are constants, a≠0) as the general form of a quadratic equation of one variable.
