Question

simplify (2x +1) (x-2) - (22-5X +2)
x-4

​

Answer 1

Answer:

$7x^2 - 29x - 2$

Step-by-step explanation:

$(2x-1)(x-2) - (22-5x+2)x-4\\= 2x^2 - 4x - x +2 - 22x+5x^2-2x-4\\= 7x^2 - 5x + 2 - 22x -2x-4\\= 7x^2 - 29x - 2$

Answer 2

Answer:

Simplify: (4x2 - 2x) - (-5x2 - 8x).

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)
