Yes! that is the correct answer I believe
Answer:
First you must rewrite the given equation in standard form:
2x^2 - 4x + 7 = 0. Here a=2, b=-4 and c=7.
The solutions are thus
-[-4] plus or minus sqrt( [-4]^2 - 4[2][7] )
x = --------------------------------------------------------
4
4 plus or minus sqrt (16 - 56)
or: x = --------------------------------------------
4
16-56 = - 40, a negative number. Thus, we must introduce the imaginary operator: sqrt (-40) = 2i*sqrt(10)
The roots are thus:
4 plus or minus 2i sqrt(10) 2 plus or minus i*sqrt(10)
x = ----------------------------------------- = ---------------------------------------
4 2
Answer:
The answer is 5/3, 1 2/3, and 1.67
Step-by-step explanation:
The answer to this problem is simple as everything between the two lines will come out to be a positive. So the equation will end up coming out to be 3x+1+2=8.
Now we add the 1 and 2....
3x+3=8
To make this problems simple we can subtract the 3 from the left side and do the same on the right side making the equation say...
3x=5
Now we can make it easier to solve but it will not be a whole number. We now divide 3 from the left and right side leaving us with....
x = 5/3
So this answer could be 5/3 , 1 2/3, and 1.67
Answer:
go on weegy your answer should pop up on there
Step-by-step explanation:
Answer:
Step-by-step explanation:
Lots of factoring here. Let's rewrite everything in its simplest, factored form:
The term (x - 4) cancels out completely, leaving us with
Let's get rid of that (x + 4) by multiplying both top and bottom by (x + 4) to get
It's obvious now that the (x + 3) term cancels out, leaving us with
Now all that's left to do is to FOIL out the numerator:
The first choice is the one you want
