Answer:
9
Step-by-step explanation:
13 - 5 = 8
8 / 2 = 4
13 - 4 = 9
Given a polynomial p(x) with leading coefficient 
and solutions 
, we have
That's why we have to find the solutions first. We complete the square by adding 3 to both sides:
From here, we continue by taking the square root of both sides:
So, the two solutions are
Which yields the factorization

Answer:
x = 10/3
Step-by-step explanation:
1.Arrange both equations so that the constant is isolated
3x - 2y = 14
6x + y = 18
2. Multiply both sides of first equation by a value that will cancel out a variable when added to the second equation
(-2) 3x - 2y = 14 (-2)
-6x + 4y = -28
3. Add both equations together
-6x + 4y = -28
<u>+ 6x + y = 18</u>
0x + 5y = -10
4. Simplify
5y = -10
y = -2
5. Substitute y-value into one of the original equations to solve for x
3x = 2y + 14
3x = 2(-2) + 14
3x = -4 + 14
3x = 10
x = 10/3
