Answer:
The solution for the given polynomial 
is 
Step-by-step explanation:
Here, the given quadratic equation is :
Now, here solving the given equation by SPLITTING THE MIDDLE TERM:
⇒ either (2x+1) = 0, or ( 2x + 1) = 0
⇒ x = -1/2 or x = -1/2
Here, in both the cases, the value of x is equal i.e x = -1/2
So, the given function has TWO IDENTICAL ROOTS.
Hence the solution for the given polynomial is
Answer:
4 + 0.32x
Step-by-step explanation:
0.32 = cost of one text message
0.32x = cost of x text messages
4 + 0.32x = monthly cost of x text messages
We have that
<span>y = -x</span>²<span>+8x
we know that
when the ball hint the ground is the x-intercepts of the graph
the x-intercepts is for y=0
so
0=-x</span>²+8x--------> x²-8x=0----> x*(x-8)=0
the solution is
x=0
x=8
the x intercepts are the points (0,0) and (8,0)
the distance between the x intercepts points =[8-0]-----> 8 ft
the answer is
8 ft
see the attached figure
2*2=4 first you multiply
4-1=3 then subtract
3+3=6 now you add and that is your answer =6
