Answer:
-6/7
Step-by-step explanation:
x2+5x+6=0
7x+6= 0
-6 -6
7x= -6
/7 /7
x= -6/7 or -0.85714285714
Answer: 
Step-by-step explanation:
Given : Nathan brings cupcakes to school and gives them to his five best friends, who share them equally.
i.e. Number of friends = 5
If c represents the number of cupcakes Nathan brings to school, then the number of cupcakes each of his friends receive is given by using division operation :_

Hence, the expression to show how many cupcakes each of his friends receive. : 
Answer:
1. 0
4. 6
Step-by-step explanation:
1. 2 x -1 + 1 ×2 = -2 + 2 = 0
2. 2x - 4 x 3 = 0
or 2x - 12 = 0
or 2x = 12
or x = 6
Answer:
Discontinuity of function occurs when x = 4 or x = -4
zero of function is when x=0
Step-by-step explanation:
We are given:

Discontinuity of the function occur when the denominator is equal to zero.
So, we need to find the values of x that makes the denominator zero.
The denominator is x^2 - 16
x^2 - 16 =0
x^2 = 16
x = ± 4
So, if the value of x = 4 or value of x=-4 then the function will be discontinuous.
Zero of the function i.e f(x)=0
So, Putting the function equal to zero and finding the value of x

So, zero of function is when x=0
