Question

factorise the following using identities
p²+8p+16​

Answer 1

Answer:

p²+8p+16

(-2²)+8(-2)+16

-4 +10 +16

5+16

21

Step-by-step explanation:

see the formula of p= -2

then the p is converted into

-2 then see the first p² =(-2²)

now we now that if the number first is - then we get ( ) breaket then (-2)+8then the p formula is -2 right then we get (-2)+8(-2) +16. right then we cut the breaket , (-2²) it will -2 and the ² if we add it will be -4 then if we cut the 8(-2) in the breaket cut it will + then 8+2=10 then -4 +10+16 then you can add it
