Question

Expand :

(i) (y – √3)²

(ii) (x – 2y – 3z)²​

Answer 1

Answer:

i)y^2+3-2√3*y

ii) x^2+ 4y^2+9z^2-4xy-6xz+12yz

Step-by-step explanation:

i)y^2 +(√3)^2 -2*√3*y

y^2+3-2√3*y

ii) x^2+(2y)^2+(3z)^2 -2*x*2y-2*x*3z +2*2y*3z

x^2+ 4y^2+9z^2-4xy-6xz+12yz

Answer 2

Answer:

(i) The expansion is y² - 2y√3 + 3.

(ii)
