सारणी पूरा कीजिए:

	प्रथम व्यंजक	द्वितीय व्यंजक	गुणनफल
(i)	a	b+c+d	______
(ii)	x+y-5	5xy	______
(iii)	p	6p2 - 7p + 5	______
(iv)	4p2q2	p2 - q2	_______
(v)	a+b+c	abc	________

हम पाते हैं:

(i) a x ( b + c + d) = a x b + a x c + a x d
                          = ab + ac + ad

(ii)  (x + y - 5) x 5xy = x x 5xy + y x 5xy + (-5) x 5xy
                             = 5x²y  + 5xy² - 25xy

(iii)  p x (6p² - 7p + 5) =  p x 6p² + p  x (-7p) + p x 5
                                = 6p³ - 7p² + 5p

(iv)   4p²q² x (p² - q²) =  4p²q² x p² + 4p²q² x (- q²⁾
                               =  (4 x 1) x p²q² x p²  + [4 x (-1)] x p²q² x q²
                               =  4p⁴q² - 4p²q⁴    

(v) (a+ b + c) x abc =  a x abc + b x abc + c x abc
                             = (1 x 1) x a x abc + (1 x1) x b x abc + (1 x 1) x c x abc
                             = (1) x a²bc + (1) x ab²c + (1) x abc²
                             = a²bc + ab²c + abc²
