-1 • (a7 - a2 + 15)
you can factor it like that
is a(a-7)-15 still acceptable?
a(a-7)-15 = \(a^2-a7-15\) also, the remaining numbers, like 15 have to be in parenthesis
Oh sorry, the question was suppose to be a^2-7a-15
I edited it
no that can't be factored
wouldn't that equal a(a-7)-15 = a^2−a7−15?
because the variable outside the parenthesis has to be common in each term -15 does not contain a
I see...thank you for you assistance
