" 18."4a^(2)-4b^(2)+4a+1

The value of the product (4a^(2)+3b)(9b^(2)+4a) at a=1, b=-2 is

factorize : 4a^2-4b^2+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)

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

If 9a^(2)+4b^(2)=18ab, then log(3a+2b)=
