Answer 2

1) (x+2)(x-5)+3x=x+2+x-5+3x=(x+x+3x)+(2-5)=4x-3

Answer 3

I can help you solve this equation. Here are the steps:

1) Expand the brackets on both sides of the equation:

(x+2)(x-5) + 3x + 2 + 12 - x(x-3) = (6-2x)(x+2)

x^2 - 3x - 10 + 3x + 2 + 12 - x^2 + 3x = 6x + 12 - 2x^2 - 4x

2) Simplify by collecting like terms on both sides of the equation:

-2x^2 + 9x + 4 = -2x^2 + 2x + 12

3) Subtract -2x^2 from both sides of the equation:

9x + 4 = 2x + 12

4) Subtract 2x from both sides of the equation:

7x + 4 = 12

5) Subtract 4 from both sides of the equation:

7x = 8

6) Divide both sides of the equation by 7:

x = 8/7

Therefore, the solution is x = 8/7.
