F (x) = x^2 - 2x + 1
f (x) = (-2)^2 - 2(-2) + 1
= 4 + 4 + 1
= 9
f (x) = ( 0 )^2 - 2 (0) + 1
= 0 - 0 + 1
= 1
0 = x^2 - 2x + 1
x^2 = 2x - 1 = 1
f (2) = 2^2 - 2(2) + 1
= 4 - 4 + 1
= 1
f (3) = 3^2 - 2(3) + 1
= 9 - 6 + 1
= 3 + 1
= 4
A - a removes both a’s from equation, then you’re left with b + bsquared, since they are unknown values you cannot combine them, even if it is the same letter, you can only add and subtract unknown values with their same letters together.

Answer:
64
Step-by-step explanation:
If the mean is 15, the sum of 5 numbers is:
Minimum value for the first four numbers would be:
Then the fifth number is:
- 75 - (1+2+3+4) = 75 - 10 = 65
So the maximum difference is:
Answer:
Step-by-step explanation:
<u>Given quadratic equation</u>:
To complete the square, begin by adding and subtracting the square of half the coefficient of the term in x:
Factor the perfect square trinomial:
To solve the quadratic, set it to zero and solve for x:
Therefore, the solution to the given quadratic equation is:
