Ok so i have this algebra homework to do and Im stuck on a few questions:
1.. (3-x)(5+x)=0
2. (x-1/2)(x+3/4)=0
3. (x+7)(2x-1)=0
Okay so thank you for your help and if its possible, could you show your working? I need to have my working shown. The 'x' I have used stand for the unknown number. Thank you so much :)

NOOO haha I need to know the answers for 'em! :O
I have dyscalculia so I find these questions almost impossible to do.
Thank you :)
