Answer 1

Как то так должно получиться

Answer 2

It seems like you've provided a series of equations and expressions. Let's break them down:

1. 2b(x-1)-3a(x-1)+c(x-1): You can factor out (x-1) from each term: (x-1)(2b - 3a + c)

2. x(a^2+b^2)+y(a^2+b^2)-z(a^2+b^2): You can factor out (a^2 + b^2) from each term: (a^2 + b^2)(x + y - z)

3. c(a-b)+b(y-x): You can factor out (a-b) from the first term and (y-x) from the second term: (a-b)(c + b(y-x))

4. a(b-c)+b^2(b-c)-7(c-b): You can factor out (b-c) from each term: (b-c)(a + b^2 - 7)

5. x(a-2+y(y-x)-3(x-y)): You can simplify this expression step by step:

   • Distribute (a-2) into the second part: x(a-2) + x(y(y-x)) - 3x(x-y)
   • Distribute x into the last two terms: xa - 2x + xy(y-x) - 3x^2 + 3xy
   • Combine like terms: xa + xy(y-x) - 2x - 3x^2 + 3xy

6. 137^2 + 137*63: Calculate this as a simple arithmetic expression: 137^2 = 18,769 137*63 = 8,631 So, the sum is 18,769 + 8,631 = 27,400

7. 0.7^3 + 0.7*9.51: Calculate this as a simple arithmetic expression: 0.7^3 = 0.343 0.7*9.51 = 6.657 So, the sum is 0.343 + 6.657 = 7.0
