a.) X^2 - 2x – 24 = 0

x^2-6x+4x-24=0

this is expressing negative 2x as the sum of two terms which are negative 6x and positive 4x

x(x-6)+4(x-6)=0

(x+4)(x-6)=0

(x+4)=0. so x=-4

(x-6)=0 so x=6

b.) x^2 - 11x + 18 =0

Mazyrski [523]

Answer:

$x^2$

Step-by-step explanation:

apply the inverse properties of logarithmic and exponential functions to simplify

$ln(e^{x^2})$

all logs has base 'e'

Inverse property of log says that

$ln(e^x)=x$ , the value of ln e=1

we apply this property in our problem. ln has same base 'e' . ln and 'e' gets cancelled

$ln(e^{x^2})$

$x^2$
