Ax^2+bx+c=0
a=2
b=-1
c=-3
b+-sqrt( b^2 - 4ac)
2a
so...
-1 +- sqrt(1 + 24)
4
-1 +- 5
4
x= -1 + 5 = 1
4
or
x= -1 - 5 = -3/2

<u>ANSWER: </u>
The vertex of given equation is (6, 32).
<u>SOLUTION:
</u>
Given, quadratic equation is
Above equation is a parabola and we need to find the vertex of that parabola. We know that, general form of the parabola is
Where, (h, k) is the vertex.
So, let us convert the given equation in parabolic equation.
Now, by comparing above equation with general form,
h = 6, k = 32 and a = -1.
Hence, the vertex of given equation is (6, 32).
Answer:
La respuesta es 102
Step-by-step explanation:
The <em><u>correct answers</u></em> are:
60°, 120°, and 180°.
Explanation:
A hexagon has six angles. A full circle is 360°; since there are 6 angles in the hexagon, it will rotate onto itself every 360/6 = 60°. This means that the hexagon will rotate onto itself at angles that are multiples of 60°; this means that 120° and 180° will also do this.
