Use the formula : (a - b)(a + b) = (a² - b²)
Hence, (4√3 + 3√2)(4√3 - 3√2) = (4√3)² - (3√2)² = 48 - 18 = 30
Hence, (4√3 + 3√2)(4√3 - 3√2) = (4√3)² - (3√2)² = 48 - 18 = 30

I used the simple arithmetic formula,
(a+b)(a-b)= a^2 - b^2
The answer comes to 30 too... please lemme know if there's anything which consumes less time!
(a+b)(a-b)= a^2 - b^2
