Question

(3+√2) (3-√3) simplify pls give ans fast

Answer 1

(3 + √2)(3 - √3)

According to the identities, (x + a)(x + b) = x^2 + (a + b)x + ab

Let a represent √2, b represent -√3 and x represent 3.

(3 + √2)(3 - √3) = (3)^2 + (√2 - √3)*3 + √2*(-√3)

(3 + √2)(3 - √3) = 9 + 3√2 - 3√3 - √6

Hope it helps :)

Answer 2

answer=9 -3root 3+3root2-root 6
= 9-3 root 1-root6
=9-3-root6(since root 1 is equal to 1 as 1 square is 1)
