Answer:
x = -3, 
Step-by-step explanation:
The given quadratic equation is: 
This can be written as: 
To solve a quadratic equation of the form 
we use the formula:
Here, a = 2; b = 3; c = - 9
Therefore, the roots of the equation are:
We get two values of 'x', viz.,
x = 
and 
⇒ x = -3, 3/2
Since the factors of the quadratic equation is asked, we write it as:
(x + 3)(x - ) = 0
because, if (x - a)(x - b) are the factors of a quadratic equation, then 'a' and 'b' are its roots.
Multiply (x + 3) and (x - to see that this indeed is the given quadratic equation.
65+50x = 55x + 20
-50x -50
65=5x+20
- 20 - 20
55=5x
55/5= 5x/5
11=x

Only the 3. option can be used. All other values dont fit
Answer:
No
Step-by-step explanation:
Start by using the distributive property to simplify 8(1/4x+3/4):
8•1/4x=2x
8•3/4=6
The equation now reads: 2x+6-3=17. Subtract 3 from six and you get 2x+3=17.
You can now proceed to answer this like any two step linear equation.
2x+3=17
-3 -3
2x=14
x=7
7 is the solution to this equation
