Answer 2

Answer:

4√7 - 8

Step-by-step explanation:

Here we have to multiply the numerator and the denominator by the conjugate of √7 + 2.

The conjugate of √7 + 2 is √7 - 2.

12  *   ((√7 - 2)             12√7 - 24

------ ---------------      =  --------------

(√7 + 2)   *(√7 - 2)       (√7)^2 - 2^2

= (12√7 - 24) / (7 - 4)

= 3(4√7 - 8) / (3)

Cancelling out 3 both in the numerator and in the denominator, we get

= 4√7 - 8

Answer: 4√7 - 8

Thank you.
