Question

find the following products:(7x+3)(2x+5)(3x-4)​

Answer 1

Answer:

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

Solution:

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

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

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

= 9x2 + 6x.

= 3x(3x + 2).

Step-by-step explanation:

Answer 2

(7x+3)(2x+5)(3x-4)

7x(2x+5)+3(2x+5)(3x-4)

(14x²+35x+6x+15)(3x-4)

(14x²+41x+15)(3x-4)

3x(14x²+41x+15)-4(14x²+41x+15)

42x³+123x²+45x-56x²-161x+60

42x³+67x²-116x+60
