Answer 1

Ответ:

1. 20-10x+x²+5 = (5-x)²

2. 24x+x²+150+(-6) = (12+x)²

3. -14x+x²+50+(-1) = (7-x)²

4. -2-6x+x²+11 = (3-x)²

5. 190+28x+x²+6 = (14+x)²

Пошаговое объяснение:

1. 20-10x+x²+5=25-2∙5∙x+x²=5²-2∙5∙x+x²= (5-x)²

2. 24x+x²+150+(-6)=144+2∙12∙x+x²=12²+2∙12∙x+x²= (12+x)²

3. -14x+x²+50+(-1)=49-2∙7∙x+x2=7²-2∙7∙x+x²= (7-x)²

4. -2-6x+x²+11=9-2∙3∙x+x²=3²-2∙3∙x+x²= (3-x)²

5. 190+28x+x²+6=196+2∙14∙x+x²=14²+2∙14∙x+x²=(14+x)²
