Identify the errors made in finding the inverse of y = x2 + 12x.

X = y^2 + 12x
y^2= x-12x
y^2=-11x
y=v-11x, for x>0

Describe the three errors.

answear:

a

step-by-step explanation: a

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

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

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

answer: y = -2.5x - 15

              (-6,0)
