Question

Упростите выражение:(C+2)(c-3)-(c-1)^2

Answer 1

= С^2 - 3C + 2C - 6 - ( C^2 - 2C + 1 ) = C^2 - C - 6 - C^2 + 2C - 1 =
= C - 7 

Answer 2

I can help you with math problems. To simplify the expression, you need to expand the brackets and then combine the like terms. Here are the steps:

(C+2)(c-3)-(c-1)^2 = C^2 - C - 6 + 2c - 3 - (c^2 - 2c + 1) = C^2 - C - 6 + 2c - 3 - c^2 + 2c - 1 = -C - 10

The simplified expression is -C - 10. I hope this helps.Ответь+подробно.+Упростите+выражение:(C+2)(c-3)-(c-1)^2
