Answer:
-4x^2 - 8x - 3
Step-by-step explanation:
f(x)= -4(x+1)^2 + 3
-4 * (x^2 +2 x + 1) +3=
-4x^2 -8x- 4 +1 =
-4x^2 - 8x - 3
Answer:
Step-by-step explanation:
(ANS)
We need to solve for the values of x by applying the method of completing the square in the given expression x² - 10x -2 = 17. The solution is shown below:
x² - 10x -2 = 17
Transpose -2 to the right side such as:
x² - 10x = 17 + 2
Perform addition of 17 and 2
x² - 10x = 19
Add + 25 in both sides
x² - 10x + 25 = 19 + 25
x² - 10x + 25 = 44
(x-5)(x-5) = 44
Where (x-5) is a perfect square, then we have:
(x-5)² = 44
x1 = +√44 -5 = 1.6
x2 = - √44 -5 = -11.6
The answers are x1=1.6 and x2 = -11.6.
