Step-by-step explanation:
Solution by completing the square for:
x2−12x+9=0
Keep x terms on the left and move
the constant to the right side
by subtracting it on both sides
x2−12x=−9
Take half of the x term and square it
[−12⋅1/2]^2=36
then add the result to both sides
x^2−12x+36=−9+36
Rewrite the perfect square on the left
(x−6)^2=−9+36
and combine terms on the right
(x−6)^2=27
Take the square root of both sides
x−6=±27−−√
Simplify the Radical term (1):
x−6=±3–√3
Isolate the x on the left side and
solve for x (1)
x=6±3–√3
therefore (2)
x=6+3–√3
x=6−3–√3
which becomes
x=11.1962
x=0.803848
Answer:
slople = -1
Step-by-step explanation:
(x₁ , y₁) = (-3, 4) & (x₂ , y₂) = (2 , -1)
![slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\frac{-1-4}{2-[-3]}\\\\\\=\frac{-1-4}{2+3}\\\\\\=\frac{-5}{5}\\\\= -1](https://tex.z-dn.net/?f=slope%20%20%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B-1-4%7D%7B2-%5B-3%5D%7D%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B-1-4%7D%7B2%2B3%7D%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B-5%7D%7B5%7D%5C%5C%5C%5C%3D%20-1)
