Answer 3

To simplify the expression (x+2)(x-5)-3x(1-2x), you can follow these steps:

1. Start by expanding the two products: (x+2)(x-5) = x(x-5) + 2*(x-5) = x^2 - 5x + 2x - 10 = x^2 - 3x - 10

   -3x*(1-2x) = -3x + 6x^2

2. Now, subtract the second expression from the first one: (x^2 - 3x - 10) - (-3x + 6x^2)

3. Distribute the negative sign in the second expression: x^2 - 3x - 10 + 3x - 6x^2

4. Combine like terms: (x^2 - 6x^2) + (-3x + 3x) - 10

5. Simplify further: -5x^2 - 10

So, the simplified expression is -5x^2 - 10.
