Question

(с-1)(с-2)+(с-3)(с-4)

Answer 1

(с-1)(с-2)+(с-3)(с-4)=с^2-с-2с+2+с^2-3с-4с+12=
2с^2-9с+14

Answer 2

C²-2c-c+2+c²-4c-3c+12 = 2c²-10c+14

Answer 3

To simplify the expression (c-1)(c-2) + (c-3)(c-4), you can use the distributive property to expand and combine like terms:

(c-1)(c-2) + (c-3)(c-4)

= c(c-2) - 1(c-2) + c(c-4) - 3(c-4)

Now, distribute the terms:

= c^2 - 2c - c + 2 + c^2 - 4c - 3c + 12

Combine like terms:

= c^2 + c^2 - 2c - c - 4c - 3c + 2 + 12

= 2c^2 - 10c + 14

So, the simplified expression is 2c^2 - 10c + 14.
