Question

factorise :4(2a + b)^2 – (a - b)^2​

Answer 1

Answer: 4{(2a^2+b^2+4ab)}-(a^2+b^2-2ab)

4(4a^2+b^2+4ab)-a^2-b^2+2ab

4(3a^2+6ab)

12a^2+24ab

2a^2+4ab

a^2+ab

Answer 2

Step-by-step explanation:

${(2)}^{2} (2a + b) {}^{2} - (a - b) {}^{2} \\ (4a + 2b) {}^{2} - (a - b) {}^{2} \\ using \: the \: property \: of \: {a}^{2} - {b}^{2} \\ (4a + 2b - a + b)(4a + 2b + a - b) \\ (3a + 3b)(5a + b)$
