I think so.r2 + 7r + 6 = [ (r+6) (r+1) ]
r2+6r-7 = (r+7)(r-1) when factored
(r+5)(r-4) The idea is to get two numbers whose product in this case is -20, and whose sum in this case s +1.
7(r-12) A 7 is taken out because it is a common factor to both terms.
If you mean: 5x+35 then when factored it is 5(x+7)
273-8 factored = 265
66 factored to get -1 = 65
It can be factored as the SQUARE OF A BINOMIAL
16m-28m factored = -12
To factor the expression 4qr - qr^3, we first notice that both terms have a common factor of qr. We can factor out qr to get qr(4 - r^2). Next, we recognize that 4 - r^2 is a difference of squares, which can be factored further as (2 + r)(2 - r). Therefore, the fully factored form of 4qr - qr^3 is qr(2 + r)(2 - r).
