x^2-(x-1)(x+3)=
x^2-(x+1)(x+3)=
x^2-(x-1)(x-3)=
x^2-(x+1)(x-3)=
Пожалуйста срочно над

Answer 1

1.х^2-(x-1)(x+3)=x^2-(x^2+3x-x-3)=x^2-(x^2+2x-3)

=x^2-x^2-2x+3=-2x+3

2.x^2-(x+1)(x+3)=x^2-(x^2+3x+x+3)=x^2-(x^2+4x+3) =x^2-x^2-4x-3=-4x-3

3.x^2-(x-1)(x-3)=x^2-(x^2-3x-x+3)=x^2-(x^2-4x+3)

=x^2-x^2+4x-3=4x-3

4.х^2-(x+1)(х-3)=x^2-(x^2-3x+x-3)=x^2-(x^2-2x-3)=x^2-x^ 2+2x+3=2x+3
