Contents
(1) Complete the table:
S. No. | First Expression | Second Expression | Product |
(1) | 5q | p + q – 2r | 5q (p + q – 2r) = 5pq + 5q2 – 10qr |
(2) | kl + lm + mn | 3k | …….. |
(3) | ab2 | a + b2 + c3 | …….. |
(4) | x – 2y + 3z | xyz | …….. |
(5) | a2 bc + b2 cd – abd2 | a2 b2 c2 | …….. |
(2) Simplify: 4y (3y+4)
(3) Simplify x (2x2 -7x+3) and find the values of it for (i) x = 1 and (ii) x = 0
(4) Add the product: a (a-b), b (b-c), c(c-a)
(5) Add the product: x (x+y-r), y (x-y+r), z(x-y-z)
(6) Subtract the product of 2x (5x-y) from product of 3x (x+2y)
(7) Subtract 3k (5k-l+3m) from 6k (2k+3l-2m)
(8) Simplify: a2 (a – b + c) + b2 (a + b – c) – c2 (a – b – c)
