Question

2. Simplify the following:
(i) (2x + 5)(3x - 2) + (x + 2)(2x - 3)
(ii) (3x + 2)(2x + 3) - (4x - 3)(2x - 1)​

Answer 1

Answer:

1) 8x^2+12x-6 2) -2x^2+23x+3

Step-by-step explanation:

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

(6x^2+11x-10)+(2x^2+x-6)

6x^2+11x-10+2x^2+x-6

8x^2+12x-16

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

(6x^2+13x+6)-(8x^2-10x+3)

6x^2+13x+6-8x^2+10x-3

-2x^2+23x+3
