Question

6) 5 (-a) (-ca) - a².​

Answer 1

Объяснение:

5(-а)(-са)-а²=5а²с-а²

Answer 2

To simplify the expression 5(-a)(-ca) - a², we can follow the order of operations (PEMDAS) and simplify each term step by step:

1. Start with the term 5(-a)(-ca): -a and -ca can be multiplied together: 5(-a)(-ca) = 5(a)(ca) = 5a(ca) = 5a²c.

2. Now, we have 5a²c - a².

Since both terms have a common factor of a², we can factor it out:

a²(5c - 1).

Therefore, the simplified expression is a²(5c - 1).
