Question

3) 4a²-b²+2a+b factorize​

Answer 1

Answer:

first arrange it:-

$4a { }^{2} + 2a - b { }^{2} + b$

then make pair of two:-2a(a+1)-b(b+1)

hope it may be right.

Answer 2

$4 {a}^{2} - {b}^{2} + 2a + b$

$( {2a})^{2} - (b)^{2} + (2a + b)$

$(2a + b)(2a - b)(2a + b)$

$(2a + b)(2a - b + 1)$
