23y(y+7) what's the answer to this problem

Hey there :)

-23y ( y + 7 ) = 0
Here it is not necessary to distribute -23y into the brackets
Why? Because if you open the parenthesis, you will have to factor again to find the possible values of y. The given form is already factored.
Whatever we do, our final value should be 0, so take them separately

-23y = 0                                           y + 7 = 0
  y = 0                                                y = - 7
