For this case we have the following expression:
The first thing we must do is to rewrite the expression as the product of two binomials.
To do this, we add similar terms.
We have then:
Then, doing distributive property we have:
Adding similar terms:
Answer:
The simplified expression is:
Subtract -6 from both sides
3x^2 + 17x + 4 - (-6) = -6 - (-6)
3x^2 + 17x + 10 = 0
factor left side of equation
(3x+2)(x+5)=0
set factors to 0
x = -2/3 OR x = -5
I would go with -5
Answer:
B. Biased Sample.
Step-by-step explanation:
The population is not only made of mothers, but there are fathers, sons, daughters, brothers and sisters, and a lot of other people. By selecting only mothers, it gears the survey to be biased towards a certain type of thinking.

Answer:
One solution
Step-by-step explanation:
In a one- variable equation has infinitely many solutions when solving results in a true statement, such as 2=2
In a one- variable equation has one solution when solving results in one value for the variable, such as x = 5
In a one - variable equation has no solution when solving results in an untrue statement, such as 2=3
So, in this case the result x = -2 belongs to the 2nd sentence where it says one solution.
Hope this helps :)
