Answer 2

no direct answers @ribhu

Answer 3

Thank you @ribhu

Answer 4

this one was merely factorisation and no intermediate steps were involved @BloomLocke367

Answer 5

@ribhu

Answer 6

\[d ^{2}-64\]
original format of standard form:
\[y=x ^{2}+ax+b\]

Answer 7

so to turn it to factored form do this...
so we would need to use the diamond method like so...

Answer 8

\[d ^{2}-64+(0)\]
I put an invisible 0 so it would be easier to view itso now we have to use the -64 and 0 for the diamond method

Answer 9

The answer was already posted.. (d+8)(d-8)

Answer 10

so find two numbers now that would multiply to the top number and add to the bottom

Answer 11

...fine
close the question then
i guess you don't need an explanation
