Question

factorise using identities p²-16​

Answer 1

Answer:

$p^{2} - 16$

$(p)^{2} - (4)^{2$            ======>             [Using $a^{2}-b^{2} Identity$]

$(p+4)(p-4)$.

Answer 2

p^2 - 16

=>( p )^2 - (4)^2

=> We know the formula that

(a)^2 -(b)^2 = (a+b) (a-b) .

So , ( p )^2 - (4)^2 = (p+4) ( p-4) .
