Question

plase help!

(x+3)^2-(x+3)-56

i have to factor completely

Answer 1

x^2 + 6x+9 -x - 3-56

x^2 +5x +9 - 59

x^2 +5x - 50
x^2 + 10x - 5x - 50
x(x+10) - 5(x+10)
(x+10)(x-5)

Answer 2

first factor as
\[((x+3)+7)(x+3)-8)\] then combine like terms in the parentheses to get
\[(x+10)(x-5)\]

Answer 3

-56=-8*7 and jus write x+3 where you would usually just write x, or make substitution so its more pleasing to the eye

let a=x+3, then a^2-a-56=(a-8)(a+7)

don't forget to sub back into x, if you do it this way

Answer 4

Satellite, you're weird
