4a^(2)+b^(2)+4ab+7a+4a+5

Factorise : 5a^(2) - b^(2) - 4ab + 7a - 7b

If a^(4) + a^(2) b^(2) +b^(4)=8, a^(2) + b^(2) + ab= 4 find ab

Which of the following is the factor of 4a^(2)+b^(2)-4ab+2b-4a+1?

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

The degree of the polynomial 3a ^(2) + 4b ^(3) - 5 ab ^(3) + 7 - 5a ^(7) b ^(5) is

Divide : 4a^(2) + 12ab + 9b^(2) - 25c^(2) by 2a + 3b + 5c

If a^(4) + a^(2)b^(2) + b^(4) = 12, a^(2) + ab+ b^(2)=4 , find ab
