earnstyle [38]

is the equation in the question written like the one in the bottom? Because for me to help you I must confirm what the equation looks like.

$\frac{a-3}{2a^{2} -7a}$ × $\frac{4a-14}{a+3}$

Log(x+3)(2x+3)+log(x+3)(x+5)=2

trasher [3.6K]

<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>

$\frac{8*( \frac{c}{c} )- \frac{3}{c} }{2*( \frac{7c}{7c})+ \frac{3}{7c} } \\ \\ \frac{ \frac{8c-3}{c} }{ \frac{14c+3}{7c} } \\ \\ \frac{8c-3}{c} * \frac{7c}{14c+3} \\ \\ = \frac{56c-21}{14c+3}$

Domain restrictions are what x values make the denominator zero.
a² + 5a - 36 = (a + 9)(a - 4)
a ≠ -9 ; a ≠ 4
