Step-by-step explanation:  x−2)(−5x+x)=0×−5x+%x+−2×−5x+−2x

2 Simplify  -5x+x−5x+x  to  -4x−4x.

(x-2)\times -4x=0\times -5x+\%x-2\times -5x-2x(x−2)×−4x=0×−5x+%x−2×−5x−2x

3 Regroup terms.

-4x(x-2)=0\times -5x+\%x-2\times -5x-2x−4x(x−2)=0×−5x+%x−2×−5x−2x

4 Simplify  0\times -5x0×−5x  to  00.

-4x(x-2)=0+\%x-2\times -5x-2x−4x(x−2)=0+%x−2×−5x−2x

5 Simplify  2\times -5x2×−5x  to  -10x−10x.

-4x(x-2)=0+\%x-(-10x)-2x−4x(x−2)=0+%x−(−10x)−2x

6 Remove parentheses.

-4x(x-2)=0+\%x+10x-2x−4x(x−2)=0+%x+10x−2x

7 Simplify  0+\%x+10x-2x0+%x+10x−2x  to  \%x+8x%x+8x.

-4x(x-2)=\%x+8x−4x(x−2)=%x+8x

8 Expand.

-4{x}^{2}+8x=\%x+8x−4x

2

+8x=%x+8x

9 Cancel 8x8x on both sides.

-4{x}^{2}=\%x−4x

2

=%x

10 Move all terms to one side.

4{x}^{2}+\%x=04x

2

+%x=0

11 Factor out the common term xx.

x(4x+\%)=0x(4x+%)=0

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
