Question

A) a(a-b) +b(a-b) b) 2m - (-P) + (-13q)​

Answer 1

1) (а-б)* (а+б)
2) 2m+p-13q

Answer 2

Ответ:

a)

$a(a - b) + b(a - b) = (a - b) \times (a + b)$

b)

$2m - ( - p) + ( - 13q) = 2m + p + ( - 13q) = 2m + p - 13q$

Answer 3

Let's simplify both of the given expressions step by step:

A) a(a - b) + b(a - b)

First, distribute the 'a' and 'b' inside the parentheses:

= a^2 - ab + ba - b^2

Now, combine like terms (ab and ba are like terms because addition is commutative):

= a^2 - ab + ab - b^2

Now, the 'ab' and '-ab' terms cancel each other out:

= a^2 - b^2

So, the simplified expression is:

a^2 - b^2

B) 2m - (-P) + (-13q)

When you have a negative sign before parentheses, you can distribute the negative sign to each term inside the parentheses:

= 2m + P - 13q

So, the simplified expression is:

2m + P - 13q
