Answer:
a. 
.
b. The axis of symmetry for 
is 
.
Step-by-step explanation:
a. The vertex form of a quadratic is given by 
, where (h, k) is the vertex.
To convert from 
form to vertex form you use the process of completing the square.
Step 1: Write 
in the form 
. Add and subtract 4:
Step 2: Complete the square 
b. The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola.
For a quadratic function in standard form, , the axis of symmetry is 
.
The axis of symmetry for is .
Look at the graph shown below.
<span>3a4-2a2+5a-10)-(2a4+4a2+5a-2)
remove first set of parentheses:
apply "-" sign to second parentheses (distributive prop):
the - of a - becomes a + :
combine like terms:
Factor out the variables that are alike:
{(1)a^4 + (-6)a^2 + 0a + (-8)}}}
0a is just 0, makea the "a" term go away:
can try to factor as squares, but it doesn't work out:
8 = (-4) x (+2) product factors cannot add to make 6. </span>
+8 means that it is a positive number
-8 means that it is a negative number
I think what you mean by: {8}, is |8| which is absolute value which means no matter the answer it is the absolute value from 0 so it’s always +
Half the distance of AC (6)
X<67/5 :) do u need the work or nah
