x^2-15x+56
-7+-8=-15
-7 x -8=56
(you can make -15x and 56 with: -7 and -8)
(x-7)(x-8) <----- thats the same formula as: x^2-15x+56
x = 7 or x = 8
check the awsers:
7^2 -15 x 7 +58 = 49 - 105 + 58 = 2 :D
8^2 - 15 x 8 +58 = 64 - 120 + 58 = 2 =D
there you go, X = 7 or 8

can anybody solve this equation?
Pawel.Anikiel wrote:what . the . fuuu?
i ment solving the equation with this method:
2x+7=4x-5 | -7
2x=4x-12 | -4x
-2x=-12 | /(-2)
x=6
