[" factories "],[a(a+b-c)-bc]

Factories: a ^(2) b^(2) - 6abc + 9c ^(2)

The following graph shows the production of cement (in lakh tons) of four factories A, B, C and D over the years The production of cement by factory B in 2009 and production of cement by factory D in 2010 together is what per cent of production by factory A in 2008 ?

bc- b -c-b- ccb

Evaluate : (vi) (a + bc ) ( a- bc ) (a^2 + b^2 c^2)

Evaluate : (ix) (a+ bc ) (a- bc) (a^2 + b^2 c^2)

The value of the determinant ,a+b+2c,a,bc,b+c+2a,bc,a,c+a+2b]| is

Prove that the following. [[a,b,c],[a^2,b^2,c^2],[bc,ca,ab]] =(b-c)(c-a)(a-b)(bc+ca+ab)

Prove that abs((a,b,c),(a^2,b^2,c^2),(bc,ca,ab))=(a-b)(b-c)(c-a)(ab+bc+ca)

ab(a-b)+bc(b-c)+ca(c-a) is equal to : ab(a-b)+bc(b-c)+ca(c-a) किसके बराबर है ?
