A) (x+9)(x+3)
B)(x+9)(x-3)
C)(x-9)(x-3)
D)(x-9)(x+3)

Answer 1

do you know how to use calculator to find fast answer?
1) press mode 3 times

2)then u find 'EQN'then press 1

3)then u can see 'UNKNOWS'but dont use the 'UNKWOWS' you must press to tge right i u can see 'DEGREE' then if you already find the DEGREE you press number 2

4)Then the 'a?' will out u can put 1 stand for X^2 then equal

5) next the 'b?' come out you put 6 stand for 6x then equal

6)final the 'c?'will come out and you put -27 then equal

7) then the answer will come out
it will be x1=3 and x2=-9

8) but if you want to put in bracket the x1=will be -3 and the x2= will be 9

so final answer
(x-3)(x+9)
