First, off, divide both sides by 4 to make things easier
2m^2+5m=3
minus 3 both sides
2m^2+5m-3=0
factor
hmm
experiment
(2m-3)(m+1), nope
(2m+3)(m-1), nope
(2m-1)(m+3), yep

(2m-1)(m+3)=0
set each to zero
2m-1=0
2m=1
m=1/2

m+3=0
m=-3

m=1/2 or -3

The following question has two parts. First, answer part A. Then, answer part B.
Arturiano [62]

Answer:

  Part A:  13.2

  Part B:  see below

Step-by-step explanation:

<u>Part A</u>:

13.245 rounded to tenths is 13.2

<u>Part B</u>:

The rule is ...

  <em>Add 1 in the number place you're rounding to if the digit to its right is 5 or more. Drop (or zero) all digits to the right of the place you're rounding to.</em>

Here, the digit to the right of the tenths place is 4, so no action is taken other than dropping digits to the right of the tenths place.
