<span>log(x-3)+log(x) = 2 + log(x+2)
---------------------------
log[(x-3)x] - log(x+2) = 2
-----
log[(x^2-3x)/(x+2)] = 2
----
(x^2-3x)/(x+2) = 2^2
-------
x^2-3x = 4x+8
x^2 - 7x - 8 = 0
Factor:
(x-8)(x+1) = 0
Positive solution:
x = 8</span>

Answer:
<h2>
(2m-7)(m+3)</h2>
Step-by-step explanation:
hello:
2m² - m - 21
∆ =b²-4ac a=2 and b= -1 and c= -21
∆ =(-1)²-4(2)(-21)=169 = 13²
m1 = (-b+√∆)/2a = (1+13)4 = 14/4 = 7/2
m2 = (-b-√∆)/2a = (1-13)4 = -12/4 = -3
the factorization is : a(m-m1)(m-m2)
2(m-7/2)(m+3) = (2m-7)(m+3)
