Question

1) а-0,25b+4ax-bx; 2) 0,6b-3,5x+1,2by-7xy;

Answer 1

1). (a-0,25b)+(4ax-bx)=(a-0,25b)+4x*(a-0,25b)=(a-0,25b)*(1+4x); 2). (0,6b+1,2by)-(3,5x+7xy)=0,6b*(1+2y)-3,5x*(1+2y)=(1+2y)*(0,6b-3,5x).

Answer 2

It seems like you've provided two algebraic expressions, and it looks like you want to simplify them. Let's simplify each expression:

1. a - 0.25b + 4ax - bx:

To simplify this expression, you can group like terms:

a + 4ax - 0.25b - bx

Now, you can factor out common terms from each pair:

a(1 + 4x) - 0.25b(1 + 4x)

So, the simplified expression is:

a(1 + 4x) - 0.25b(1 + 4x)

2. 0.6b - 3.5x + 1.2by - 7xy:

Again, let's group like terms:

0.6b + 1.2by - 3.5x - 7xy

Now, factor out common terms:

0.6b(1 + 2y) - 3.5x(1 + 2y)

So, the simplified expression is:

0.6b(1 + 2y) - 3.5x(1 + 2y)

These are the simplified forms of the given expressions.
