Question

show that x+1and 2x-3 are factors of 2x cube - 9x square+ x+12​

Answer 1

Answer:

To prove that (x + 1) and (2x - 3) are factors of 2x3 - 9x2 + x + 12 it is sufficient to show that p(-1) and p(3/2) both are equal to zero. Hence, (x + 1) and (2x - 3) are the factors 2x3 - 9x2 + x + 12.

Answer 2

Answer:

p(-1) and p(3/2) both are equal to zero.

Step-by-step explanation:

To prove that (x + 1) and (2x - 3) are factors of 2x3 - 9x2 + x + 12 it is sufficient to show that p(-1) and p(3/2) both are equal to zero. Hence, (x + 1) and (2x - 3) are the factors 2x3 - 9x2 + x + 12
