The first set of parentheses is unnecessary, so just drop it.
The second set of parentheses has a negative sign to its left.
To simplify the second set of parentheses, change every sign inside the parentheses. Then combine like terms.
<span>(–x – 2) – (4x + 3) =
= - x - 2 - 4x - 3
= -x - 4x - 2 - 3
= -5x - 5

M = number
2m+25 is the correct expression

Answer:
134568
Step-by-step explanation:
go go go
<span>8 5/9 + 1 1/5
8+1 = 9
5/9 + 1/5 = 25/45 + 9/45 = 34/45
9 34/35 is the answer</span>
To factor this notable trinomial, you have to find two numbers that summes give -5 and multiplied give 6*(-25) = -150
Then let's call n1 and n2 the two numbers and a the number before x^2 (6)
ax^2+sx+fn = (ax + n1)(x + n2/a)
Numbers are -15 and +10
-15+10 = -5
-15*10 = -150
So
(6x-15)(x + 10/6)
Or write it as a sum
6x^2 + 10x - 15x - 25
And factor
6x^2 + 10x = 2x(3x+5)
-15x-25 = -5(3x+5)
(2x-5)(3x+5)
