`9(2a-b)^2-4(2a-b)-13`

If 4(a+2)^(2)-9a+2(2a^(2)-1)=4(b+2)^(2)-9b+2(2b^(2)-1)=15 where a,b in R and a>b then find the value of 8(a-b)

What is the HCF of a^(2)b^(4)+2a^(2)b^(2) and (ab)^(7)-4a^(2)b^(9) ?

Factorise : (1)/(4)(a+b)^(2) - (9)/(16)(2a - b)^(2) .

Factorise: 4(2a - b+c) ^(2) - 9 ( a+b- c) ^(2)

Factorise the using the identity a ^(2) - 2 ab + b ^(2) = (a -b) ^(2). 9y ^(2) - 4 xy + ( 4x ^(2))/( 9)

Verify identity (a + b)(a - b) -= a^(2) - b^(2) geometrically by taking a = 13 units, b = 9 units

What is the HCF of a^2b^4+2a^2b^2 and (ab)^7 - 4a^2b^9

Factorise the using the identity a ^(2) -b ^(2) = (a +b) (a-b). ( 4x ^(2))/(9) - ( 9y ^(2))/( 16)
