x%5E2-4x+=+28-+7x
x%5E2%2B3x-28=0
%28x-4%29%28x%2B7%29=0
Two solutions:
x-4=0
highlight%28x=4%29
.
.
.
x%2B7=0
highlight%28+x=-7%29
.
.
.
6x%283x+%2B+18%29%28x-+9%29+=+0
Three solutions:
6x=0
highlight_green%28x=0%29
.
.
3x%2B18=0
3x=-18
highlight_green%28x=-6%29
.
.
x-9=0
highlight_green%28+x=9%29
