Beginning

The lesson greeting.

The teacher sets the lesson objectives, 

letting students know what to anticipate from the lesson.

Then to create a positive learning environment the teacher asks students

to start the lesson giving each other compliments about appearance, job performance, talent, etc. and also practice accepting compliments.

Students greet the teacher

Give each other compliments

Exercise 1

Factorize the square trinomial

х²-8х+15; х²-11х+30 ; 3х²-5х-8;

х²-16х+60; х²+20х-96; 3х²+4х-7;

х²-4х-77 ; х²+10х-24; -9х²+8х+1;

х²+5х-14 ; х²-4х-96 ; 5х²+2х-3;

5х²-10х-15 ; 5х²+9х-2; х²-21х+110;

Exercise 3

Matching

They will factorize quadratic equations

х²-8х+15=(x-3)(x-5)

х²-11х+30=(x-5)(x-6)

3х²-5х-8=(x+1)(3x-8)

х²-16х+60=(x-6)(x-10)

х²+20х-96=(x+24)(x-4)

3х²+4х-7=(3x-7)(x-1)

х²-4х-77=(x+7)(x-11)

х²+10х-24=(x+12)(x-2)

-9х²+8х+1=(-x+1)(9x+1)

х²+5х-14=(x+7)(x-2)

х²-4х-96=(x+8)(x-12)

5х²+2х-3=5(x+1)(x-3)

5х²-10х-15=5(x+1)(x-3)

5х²+9х-2=(x+2)(5x-1)

х²-21х+110=(x-10)(x-11)

Students will factorize and will simplify trinomials.

Students match each equation with their name .
