Question

(p + q)2 – (a - b)2 + p + q- a + b​

Answer 1

Answer:

(p+q-a+b)(p+q+a-b+1)

Step-by-step explanation:

The question is:-

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

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

$using \: a {}^{2} - b { }^{2} = (a + b)(a - b)$

[{(p+q)+(a-b)}{(p+q)-(a-b)}] + (p+q-a+b)

=(p+q-a-b)(p+q-a+b)+ (p+q-a+b)

=(p+q-a+b)(p+q+a-b+1)
