Answer:
How do you find the sum of factors of a quadratic equation?
Let r and s be the factors for the quadratic equation such that x^2+Bx+C=(x−r)(x−s) where sum of factors (r+s)=−B and the product of factors rs = C r = -2 - u s = -2 + u Two numbers r and s sum up to -4 exactly when the average of the two numbers is \frac{1}{2}*-4 = -2.
How do you solve a quadratic equation?
Quadratic equations such as this one can be solved by completing the square. In order to complete the square, the equation must first be in the form x^{2}+bx=c.

Answer:
Step-by-step explanation:
If the equation of the of the hyperbola is , then the eccentricity, and the directrices are and the foci are (± ae,0).
Now, given that ae = 4 and ......... (1)
So,
⇒ a² = 8
⇒ a = 2√2 units.
Now, from equation (1) we get, ae = 4
⇒ e = √2 as a = 2√2
Now,
⇒
⇒ b² = 8
Hence, the equation of the hyperbola is

the only thing you need to do is separate m:
2/7m= 3/14 + 1/7
2/7m= 5/14
m= (5/14)/(2/7)
m= 5/14 × 7/2
m= 35/28
m= 5/4
Answer
Write an expression for the number of pencils Maggie gives to jamil.
To prove
Let us assume that the number of pencils Katie have = x
As given
Katie gives Maggie half of her pencils.
As given
Maggie keeps 5 and gives the rest to jamil.
Thus
Therefore the expression for the number of pencils Maggie gives to jamil are 
.
