Answer:
m = - 2.27 or m = 16.27
Step-by-step explanation:
Given
m² - 14m - 37 = 0 ( add 37 to both sides )
m² - 14m = 37
To complete the square
add ( half the coefficient of the m- term )² to both sides
m² + 2(- 7)m + 49 = 37 + 49, that is
(m - 7)² = 86 ( take the square root of both sides )
m - 7 = ± 
( add 7 to both sides )
m = 7 ± , that is
m = 7 - ≈ - 2.27 or m = 7 + ≈ 16.27

Here's a hint on how to add negative# and positive numbers:
Same team ...Yay its a positive
ex:
-2+ -4=6
2+7=9
Opposite team ... Nay its a negative
ex:
-23+2=-21
-22+12=-10
-15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
6 = -2x - 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Addition Property of Equality] Add 6 on both sides: 12 = -2x
- [Division Property of Equality] Divide -2 on both sides: -6 = x
- Rewrite: x = -6
First find out how much interest earned each month by multiplying .07 x 250.00 = 17.50.
Now Mr. Smith deposits 250.00 + 17.50(interest earned) = 267.50 per month
New monthly deposit is 267.50
(New monthly deposit) 267.50 x 39 (months) = 10,432.50
<span>Mr. Smith will have 10,432.50 in the account after 39 months. </span>
