Answer:
3(x + 1)(3 - x).
Step-by-step explanation:
(x + 3)^2 - 4x^2
Using the identity a^2 - b^2 = (a - b)(a + b), we have
(x + 3 - 2x)(x + 3 + 2x)
= (-x + 3)(3x + 3)
= 3(x + 1)(3 - x)
2(x+4)-6
Here,Solution
or,(2x+8)-6
or,2x+2
1-Yes/For example x=29
2-No
3-No
4-No
5-Yes/For example x=4
Good Luck :)
