Answer 9

\(3\times 9\) is \(-27\)٫ did you mean \(-27\) instead of \(-26\)?

Answer 10

no...

Answer 11

again you can use foil
(3x+1)(x-9)
fronts 3x * x = 3x^2
outers : 3x * -9 = -27x
inners : 1 * x = x
lasts-9 * 1 = -9
add everything back together
3x^2 - 27x + x - 9
combine like terms
3x^2 - 26x - 9
