Order the steps to solve the equation log(x^2-15)=log(2x) form 1 to 5

nasty-shy [4]

Answer:x=-5 and x=3

Step-by-step explanation:

log(x^2-15)=log(2x)

Cancel log at both sides we get

x^2-15=2x

Collect like terms

x^2-2x-15=0

x^2-3x+5x-15=0

x(x-3)+5(x-3)=0

(x+5)(x-3)=0

x+5=0 x-3=0

x=-5 x=3

What are the answers for question 1 and 2??

xeze [42]

Answer:

1) Answer: 3) $~~x = -3 \pm \sqrt{7}$

2) Answer: 3) 2 and -6

Step-by-step explanation:

1)

$(x + 3)^2 = 7$

$x + 3 = \pm \sqrt{7}$

$x = -3 \pm \sqrt{7}$

Answer: $3)~~x = -3 \pm \sqrt{7}$

2)

$2(x + 2)^2 - 4 = 28$

$2(x + 2)^2 = 32$

$(x + 2)^2 = 16$

$x + 2 = \pm \sqrt{16}$

$x + 2 = \pm 4$

$x + 2 = 4$ or $x + 2 = -4$

$x = 2$ or $x = -6$

Answer: x = 2 or x = -6
