Answer:

Step-by-step explanation:
Given;
x² - 2x - 1 = 0
Solve by completing the square method;
⇒ take the constant to the right hand side of the equation.
x² - 2x = 1
⇒ take half of coefficient of x = ¹/₂ x -2 = -1
⇒ square half of coefficient of x and add it to the both sides of the equation


⇒ take the square root of both sides;

Therefore, option B is the right solution.

Answer:

Step-by-step explanation:
In order to find g we have to use the formula for finding the slope of the line passing through two points that's

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are (g, -1) and (2, 5) and m = 3/2
We substitute it into the equation and find g
That's

We have the final answer as
<h3>g = - 2</h3>

Remember PEMDAS - parentheses, exponents, multiply, divide, add, subtract
because multiply come before subtract, your first step would be 1/2 x 2 = 1
next, you subtract -> 15 - 1 = 14
14 is your answer
