(-2)^2 + 3(-2) + 1
4-6+1
-1
One way is to estimate
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
the number 61 is between 49 and 64 therefor the square root of 61is between the intigers 7 and 8 or -7 and -8
X = 26.89352
1. remove parenthesis
2. divide both sides by 14
Answer:

Step-by-step explanation:
Option 1:
Using the following rule:

Put in our expression,
a = 2
n = 3
m = 2


Option 2:
Using the following rule:

Since our expression is the same as multiplying 2³ with itself, we can write it as a multiplication.

If we compare this with
, we can see that
a = 2
n = 3
m = 3 (in this case, n and m are equal)


Answer: 
three squared minus two thirds

three square = 3 x 3 = 9

Least common factor of 1 and 3 is 3

Three squared minus two third is twenty five by three.
