Answer:D
Step-by-step explanation:
Instead of a long explanation, I will just tell you a small tip I.e. A and D are same except for one sign on the term +26x. In order get the terms with x u need to multiply the terms regarding the final product as x.
Here it is 7 times 5x minus 3 times 3x,
which is 35x-9x=26x.
On D, the 26 is positive.
Answer: (D)
Step-by-step explanation:
(2x^2+5x-3) (3x+7)
6x^3+14x^2+15x^2+35x-9x-21
6x^3+29x^2+26x-21
