4. Simplify: (4 – 5) – (13 – 18 + 2).

Solution:

(4 – 5) – (13 – 18 + 2).

= -1-(13+2-18).

= -1-(15-18).

= -1-(-3).

= -1+3.

= 2.

5. What is |-26|?

Solution:

= 26.

6. Multiply: (x – 4)(x + 5)

Solution:

(x – 4)(x + 5).

= x(x + 5) -4(x + 5).

= x2 + 5x – 4x – 20.

= x2 + x - 20.

7. Factor: 5x2 – 15x – 20.

Solution:

5x2 – 15x – 20.

= 5(x2 – 3x – 4).

= 5(x2 – 4x + x – 4).

= 5{x(x - 4) +1(x - 4)}.

= 5(x-4)(x+1).

8. Factor: 3y(x – 3) -2(x – 3).

Solution:

3y(x – 3) -2(x – 3).

= (x – 3)(3y – 2).

9. Solve for x: 2x – y = (3/4)x + 6.
