Question

can I factor a^2 - a7 - 15 as a(a-7)-15?

Answer 1

-1 • (a7 - a2 + 15)

Answer 2

you can factor it like that

Answer 3

is a(a-7)-15 still acceptable?

Answer 4

a(a-7)-15 = \(a^2-a7-15\)
also, the remaining numbers, like 15 have to be in parenthesis

Answer 5

Oh sorry, the question was suppose to be a^2-7a-15

Answer 6

I edited it

Answer 7

no that can't be factored

Answer 8

wouldn't that equal a(a-7)-15 = a^2−a7−15?

Answer 9

no

Answer 10

because the variable outside the parenthesis has to be common in each term
-15 does not contain a
