Question

Answer 1

1) \(x^2-x\) 

\(=x\left(x-1\right)\)

2) \(x^2-8x\) 

\(=x\left(x-8\right)\)

3) \(x^2-12x\)

\(=x\left(x-12\right)\)

4) \(x^3-4x\) 

\(=x\left(x^2-4\right)\)

5) \(3x^2-x\) 

\(=x\left(3x-1\right)\)

6) \(2xy+y^2\)

\(=y\left(2x+y\right)\)

7) \(x^2-xy\) 

\(=x\left(x-y\right)\)

8) \(x^3-x^2y\) 

\(=x^2\left(x-y\right)\)

Answer 2

1: =x*x-x*1

=x(x-1)

2: =x*x-8*x

=x(x-8)

3: =x*x+12*x

=x(x+12)

4: =x(x^2-4)

=x(x-2)(x+2)

5: =x*3x-x*1

=x(3x-1)

6: =y*2x+y*y

=y(2x+y)

7: =x*x-x*y

=x(x-y)

8: =x^2*x-x^2*y

=x^2(x-y)
