The solutions to the quadratic equation
are:

Step-by-step explanation:
Considering the equation

The first step is to divide all the terms by the coefficient of
which is 2.
so


Lets now solve the equation by completeing the remaining steps
Write equation in the form: 
Solving for
,





Completing the square

Since, you had required to know the first step in completing the square for the equation above, I hope you have got the point, but let me quickly solve the remaining solution.
For
the solution are 
Solving


∵ Applying imaginary number rule 



Similarly, solving

∵ Applying imaginary number rule 

Therefore, the solutions to the quadratic equation are:

All you have to do is find the LCD of the number of hours Mark and Frank uses to paint a room.
Mark - 3
Frank - 4
So list the numbers that are a result of a number and 3 and 4
(example: 4 x 1 = 4, 3 x 3 = 9)
3 - 3, 6, 9, 12, 15
4 - 4, 8, 12, 16
The list goes on and on but what we need to get is the LCD so it means it's the least number that 3 and 4 have in common.
3 and 4 both have 12 so The LCD of 3 and 4 is 12.
Another way of finding the LCD could be multiplying the numbers together, but it's not always gonna be the least number. Remember that LCD stands for Least Common Denominator.
How many hours would it take Mark and Frank to paint the room together at their respective rates?
The answer is - 12 hours
Answer:
<h2>d = 8</h2><h2>g = 2</h2>
Step-by-step explanation:
8d + 4 = 5d + 28
Group like terms
That's
8d - 5d = 28 - 4
3d = 24
Divide both sides by 3
d = 8

Cross multiply
we have
7(7g + 8) = 38.5(4)
49g + 56 = 154
49g = 154 - 56
49g = 98
Divide both sides by 49
g = 2
Hope this helps you

Answer: The value of x is 2
Step-by-step explanation:
x + 7 =3x + 3
-x -x
7= 2x + 3
-3 -3
4= 2x
x= 2
