Question

A) (c - 2)(c + 3) - c²​

Answer 1

1) (c - 2)(c + 3) = с²+3с-2с-6 = с²+с-6

2) с²+с-6-с² =  с-6

Ответ: с - 6

Answer 2

Ответ:

С квадрат+ 3с-2с-6-с квадрат =0

С квадрат пен с квадрат жойылып кетеді

3с-2с-6 =0

С-6 =0

С=6

Answer 3

Let's simplify the expression:

A) (c - 2)(c + 3) - c²

First, apply the distributive property to expand the product of the two binomials:

= (c * c + c * 3 - 2 * c - 2 * 3) - c²

Now, simplify each term within the parentheses:

= (c² + 3c - 2c - 6) - c²

Next, combine like terms within the parentheses:

= (c² + c - 6) - c²

Now, notice that the c² terms cancel out:

= c² + c - 6 - c²

The c² terms cancel out, leaving:

= c - 6

So, the simplified expression is:

c - 6
