To find 
, Beau found 
and 
. He said that since 5 is between 4 and 9, , is between 2 and 3. Beau thinks a good estimate for , is 
Is his estimate high or low? How do you know?
Answer:
The estimation is high because 5 is very close to 4 so will also be very close to 
which is lower than the estimate
In order to get a good estimate
The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them
i.e
From here we can see that lies between 2.2 and 2.3 but is closer to 2.2
So a good estimate for is 2.2
Step-by-step explanation:
Remember to make the polynomials to equal zero, one or the other polynomial must equal zero. So...
2x-3 = 0
2x= 3
x=3/2
and
4x+5 = 0
4x = -5
x = -5/4
So the answers are x=3/2 and x = -5/4
Hope this helps!
