The solutions or roots to this equation is found by solving for x. We can do this a couple ways either by FOIL or quad formula
3x^2+6x+6=0
3(x^2+2x+2)=0
x^2+2x+2=0 we cant FOIL this out so we use the quad formula
x= [(-b+\-sqrt(b^2-4ac))/2a]
x= -2+\- sqrt(4-4(1)(2))/2(1)
x= -1 +i , -1 - i
So we have complex roots since our quad formula returned a negative number. Whenever the quad formula answer is positive we have two roots/solutions, when it is zero we have one root/solution, and whenever it is negative we have Complex roots/solutions
Hope this helps. Any questions please just ask. Thank you.
The solution is
We group like terms, to obtain;
Simplify to get,
We further simplify to get;
This can also be rewritten as;
Or
![(-\infty 3] \cup (18,+ \infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%203%5D%20%5Ccup%20%2818%2C%2B%20%5Cinfty%29)
This can be represented on the number line as shown in the diagram.
Answer:
Do I have to also use what is classified as 'proper english'(Grammatically correct and suitable) for the answer I write
Step-by-step explanation:
Answer:
4√15
Step-by-step explanation:
The geometric mean of x and y is √(xy).
So here we have:
√(12*20)
= √240
= √(16*15)
= √16√15
= 4√15.
Using two points to find the slope use
y2-y1/x2-x1
i chose points (0,4) and (2,14)
14-4/2-0
10/2
5
The slope is 5
