To find:
the true statement
Solution:
Here,
To find the zeroes of 
, put 
So, zeroes are 
and 
None of the given options is correct.
You have to <em>FOIL</em> (multiply the first, then outer, then inner, then last)
(x-2)(x+4)
First: multiply x by x to get x².
Outer: multiply x by 4 to get 4x.
Inner: multiply -2 by x to get -2x.
Last: multiply -2 by 4 to get -8.
This gives you:
x² + 4x - 2x - 8
Combine like terms to get your final answer:
x² + 2x - 8
Hope this helped!! xx
If you calculate the problem correctly you should end up with:
(A)-(3)
Which equals:
= -3
Hope this helps... have a good day!
