Question

7. Simplify the following:
(i) 4x (3x - 2) - 3x (2x + 4)
(ui) 4x+ (x - 3) + 3x+ (x - 4) - 5x+ (x - 5)​

Answer 1

Step-by-step explanation:

(i) 4x(3x-2) - 3x(2x+4)

solution☆ => (12x-8x) - (6x+12x) ....use distributive law

=> 12x - 8x - 6x - 12x

=> 4x - 18x => -14x

(ii) 4x + (x-3) + 3x + (x-4) - 5x + (x-5)

solution ☆ => 4x + x - 3 + 3x + x - 4 - 5x + x - 5

=> 4x + 3x - 5x + x + x + x -3 - 4 - 5 ....collect the like terms

=> 2x + 3x - 12

=> 5x - 12
