Identify a solution of the equation: log2x+log(x−5)=2

Harrizon [31]

Answer:

3.x= 10

Step-by-step explanation:

log 2x + log (x - 5) = 2
log (2x(x - 5)) = 2
2x(x - 5) = 10²
2(x² - 5x) = 100
x² - 5x - 50 = 0
x² + 5x - 10x - 50 = 0
x(x + 5) - 10(x + 5) = 0
(x - 10)(x + 5) = 0
x = 10
x = -5, this root is discounted as log should be positive.

Correct choice is 3.

2x²+3x²+3.(-1) =5x.x+5x .1

mash [69]

$\\ \sf\longmapsto 2x^2+3x^2+3(-1)=5x.x+5x.1$

$\\ \sf\longmapsto 5x^2-3=5x^2+5x$

$\\ \sf\longmapsto 5x^2-5x^2-3=5x$

$\\ \sf\longmapsto 5x=-3$

$\\ \sf\longmapsto x=\dfrac{-3}{5}$
