Answer:
Add 36 to each side
x = 6±sqrt(30)
Step-by-step explanation:
x^2−12x=−6
Take the coefficient of x
-12
Divide by 2
-12/2 = -6
Square it
(-6)^2 = 36
Add 36 to each side
x^2−12x+36=−6+36
( x-6)^2 = 30
Take the square root of each side
x-6 = ±sqrt(30)
Add 6 to each side
x-6+6 = 6±sqrt(30)
x = 6±sqrt(30)
Answer:7.3 repeating
Step-by-step explanation:
First, since these are right across from each other, they are equal. So (x+16)=(4x-5)
Then you would subtract the 4x from both sides. Making the equation (-3x+16) = (-5)
Subtract the 16 from both sides making it a -3x=-22
To turn it positive, divide everything by negative 1 making the equation 3x=22
Divide 22 by 3 and you get your answer.
