Jake is solving x^2-6x+5=0 by completing the square his steps are shown below step 1. x^2-6x=-5 step 2. x^-6x+9=-5+9 step 3. (x-6)^2=4 Step 4. sq root (x-6)^2=sq root 4 step 5. x-6=+- 2 step 6. x=6+-2 step 7. x=8 and x =4. which step is Jakes error in.

Jake's error in step 3

Step-by-step explanation:

we have

Complete the square

step 1

Group terms that contain the same variable, and move the constant to the opposite side of the equation

step 2

Complete the square. Remember to balance the equation by adding the same constants to each side

step 3

Rewrite as perfect squares

Jake's error in step 3

He placed 6 instead of 3 in the left side

step 4

take square root both sides

step 5

step 6

step 7

x=5 and x=1

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
