Step-by-step explanation:

x² - 8 = 0

taking 8 to the RHS:

x² = 8

taking sq. root on both sides:

√8 can be written as √(2 × 2 × 2)

2 comes out of the "Sq. root" leaving a 2 behind.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

4x² - 5 = 0

taking 5 to the RHS:

4x² = 5

taking sq. root on both sides:

sq. root of 4 is 2.

taking 2 to the denominator on the RHS:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

2x² - 10 = 0

taking 2 common:

2(x² - 5) = 0

if we take 2 to the RHS, it disappears as 0 divided by any number is again 0

x² - 5 = 0

taking 5 to the RHS:

x² = 5

taking sq. root on both sides:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

2x² = 100

dividing both sides by 2:

x² = 50

writing 50 as 25 × 2 (product of a square and some number)

x² = 25 × 2

taking sq. root on both sides:
