Question

SOLVE BY COMPLETING THE SQUARE ​

Answer 1

Answer:

X=1/3or1/4

Step-by-step explanation:

12x^2-7x+1=0

12x^2-4x-3x+1=0

4x(3x-1)-1(3x-1)=0

(3x-1)(4x-1)=0

3x-1=0

3x=1

X =1/3

4x-1=0

4x=1

X=1/4

Answer 2

Answer:

Completing the square method is now deleted. This method will not come in 2021 exams.

Step-by-step explanation:

Discriminant = b^2 -4ac

= (-7)^2 - 4(12)(1) =49-48= 1

x= (-b +√D)/2a | x=(-b-√D)/2a

x= -(-7)+√1/2(12). | x= -(-7)-√1/ 2(12)

x= 7+1/24. |. x= 7-1/24

x= 8/24. |. x = 6/24

x= 1/3. |. x= 1/4
