10*(2a+b)^(2)-6a-3b-4

Factorise : (2a + b)^(2) - 6a - 3b - 4

factorize ( i ) 4(a+b)-6(a+b)^(2) (ii) 8(3a-2b)^(2)-10(3a-2b)

Simplify : 6a^(2)+3ab+5b^(2)-2ab-b^(2)+2a^(2)+4ab+2b^(2)-a^(2) .

Simplify: 4a b(a-b)-6a^2(b-b^2)-3b^2(2a^2-a)+2a b(b-a)

Simplify: 4ab(a-b)-6a^(2)(b-b^(2))-3b^(2)(2a^(2)-a)+2ab(b-a)

The factors of 8a^3+b^3-6a b+1 are (a) (2a+b-1)(4a^2+b^2+1-3a b-2a) (b) (2a-b+1)(4a^2+b^2-4a b+1-2a+b) (c) (2a+b+1)(4a^2+b^2+1-2a b-b-2a) (d) (2a-1+b)(4a^2+1-4a-b-2a b)

Add the following 3a+6a^2b+4b,2b-9ab^2-6a,-6a-7b+2a^2b

Multiply 6a^(2)b^(3) and -4a^(3)b^(4) .

Find the sum of the expressions - 3a ^(2) + 2 ab - 4b^(2) and - 6a ^(2) + 4b.

Divide : 15a^(3)b^(4) - 10a^(4)b^(3) - 25a^(3)b^(6) by -5a^(3)b^(2)
