2. Simplify the following and verify the results for the given values.
(i) (x - 4xy + y)(x - 2y) ; X = 3, y = 2
(ii) (7xºy - 32) (x + y + z) ; x = 1, y = 1, Z=-1
(iii) (4a2 - 6ab + 9b2) (2a + 3b); a = 2, b= 1
(iv) (m? - 10 m + 25) (m-5); m = -2
(v) (p2 + O2 + 2) (pq + r) ; p = 2, q = -3, r = 1
(vi)
(*P = xy )(x+y+ vº);
x+y+y?) ; x = 2, y = 2​

Answer 1

I can tell you how to verify it is like you just need to fill the given values at place of x and y ....

Answer 2

Answer:

value: x=3;y=2

(I) (x-4xy+y)(x-2y)

solu: (3-4×3×2+2)(3-2×2)

= (3-24+2)(3-4)

= (3+2-24)(-1)

= (5-24)(-1)

= (-19)×(-1)

= 19 Ans...
