" 27."9-a^(2)+2ab-b^(2)

Verify the identity (a + b)^(2) -= a^(2) + 2ab + b^(2) geometrically by taking a = 5 units, b = 9 units

Divide : 18a^(3)b^(2) - 27 a^(2)b^(3) +9ab^(2) by 3ab

For real a, b and c if a^(2) + b^(2) + c^(2) = ab + bc + ca , then find the value of (a + b + c)^(2) A. 9a^(2) B. 81 a^(2) C. 27 a^(2) D. 24 a^(2)

Factorles: 12a ^(2) b- 9ab^(2) + 6ab

Factorise the using the identity a ^(2) + 2 ab + b ^(2) = (a + b) ^(2) 9x ^(2) + 2 xy + (y ^(2))/(9)

Factorise the using the identity a ^(2) + 2 ab + b ^(2) = (a + b) ^(2) a ^(2) x ^(2) + 6ax + 9

Factorise the using the identity a ^(2) + 2 ab + b ^(2) = (a + b) ^(2) 9x ^(2) + 30 x + 25

Factorise the using the identity a ^(2) + 2 ab + b ^(2) = (a + b) ^(2) 4x ^(2) + 12 x + 9

Factorise the expression using the identity a ^(2) + 2 ab + b ^(2) = (a + b) ^(2) x ^(2) + 6x + 9
