Question 361342: Hi, I was wondering if someone could possibly help me. I am supposed to do these homework questions in my Algebra class, but I am having a hard time getting started. I don't know what steps to go through to obtain the answer. The back of the book shows the answers, but that doesn't help me much. I need to show I got to the answer. If anyone could possibly assist me, by showing me how you obtained the answer, I would be forever grateful! :o)
Section 11.2, Pg. 762, #3.
Directions: Solve each equation using the quadratic formula, simplify solutions, if possible.
〖2x〗^2-7x=-5 (the first part should read 2x squared)
the answer it shows in the back of the book is: {1,5/2}
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! a)Find vertex of quadratic
g(x)=(x-2)^2-1
Vertex: (2,-1)
-----
b) determine the # of x intercepts
Since the vertex is below the x-axis and since
the parabola opens upward, it intersects the
axis at two points.
-------------------------------
C)graph this quadratic function by 2 points on the parabolax---
Solve (x-2)^2-1 = 0
x-2 = 1 or x-2 = -1
x = 3 or x = 1
----
