Question

What are the solutions to the equation (x – 6)(x + 8) = 0?

x = –6 or x = 8
x = –6 or x = –8
x = 6 or x = –8
x = 6 or x = 8

Answer 1

The third option mam. 

Answer 2

x=6 and x=-8

To solve this, you would treat x-6=0 as one equation, you add 6 to each side to get rid of -6, hence you would get x=6.

Same goes for x+8=0, subtract 8 from each side to get rid of the +8, then you get x=-8
