(x-1)² = 50
x-1 = <span>±</span>√50

x-1 = -5√2   or   x-1 = 5√2
x = 1-5√2          x = 1+5√2

(x-1)²=50
Square root both side
√(x-1)²=√50
x-1=±√50
Add 1 to each side
x-1+1=1±5√2
x=1±5√2 is your correct answer and if you want me to solve it, here will be the answer.
x=1±5√2
x=1+5√2
x≈8.1

x=1-5√2
x≈-6.1. Hope it help!

The vertex of the graph of y = -4(x + 3)2 + 2 is ( , )
andrezito [222]

Answer:

Step-by-step explanation:

This quadratic is of the form

y=-a(x-h)^2+k where h and k are the coordinates of the vertex. Notice that inside the parenthesis it very specifically follows the format (<u>x -</u> h)². That means that if you have something like what we have here, ( x + 3)^2, it was originally (x - (-3))^2, and the value for h is -3. k is much simpler to determine. Our 2 at the end is a +2, so the k is 2. The vertex then is (-3, 2).
