I need help

see explanation

Step-by-step explanation:

Using the rule of radicals

× ⇔

Given

(2 - 5 )(4 - 6 )

Each term in the second factor is multiplied by each term in the first factor, that is

2(4 - 6 ) - 5(4 - 6 ) ← distribute both parenthesis

= 8 - 12 - 20 + 30 → *

Simplify and

= = × = 2

= = × = 2

Back to *

= 8 - 12 - 20(2 ) + 30(2 )

= 8 - 12 - 40 + 60
