Answer:
2
6,6,6,6,6,6=more than 5
7,7,7,7,7=has exactly 5 members
Step-by-step explanation:
x2 - 4x - 12
Finding factors of 12 then
x2 - 6x + 2x - 12
x( x - 6) + 2 (x - 6)
So the factors are (x+2) (x-6)
<span>3x^2 + 18x + 15 = 0
15 + 18x + 3x2 = 0
3(5 + 6x + x2) = 0
</span>3((5 + x)(1 + x)) = 0
5 + x = 0
5 + -5 + x = 0 + -5
Combine like terms: 5 + -5 = 0
0 + x = 0 + -5
x = 0 + -5
x = -5
<span>--------------------------------------------
1 + x = 0
x=-1
-5,-1 </span>
(2x-11)(2x+11) is the answer
