As already described above, the prime polynomial is that which can no longer be factored to yield a much simpler terms. From the given choices, that which cannot be factored is letter C.

Answer:

The correct option is c.

Step-by-step explanation:

Option a,

8x^2-10x-3

8x^2-12x+2x-3

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

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

A prime polynomial cannot be written as a product of lower-degree polynomials. Therefore option a is not prime.

Similarly find the factors of other expressions.

8x^2+2x-3

8x^2-6x+4x-3

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

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

Therefore option b is not prime.

8x^2-6x-3

This polynomial factored further and cannot be written as a product of lower-degree polynomials.  Therefore it is prime and option c is correct.

8x^2+23x-3

8x^2+24x-x-3

8x(x+3)-(x+3)

(8x-1)(x+3)

Therefore option d is not prime.

x+7-7=12-7
x=5
therefore the required number is 5

aev [14]
A is x times larger than B
4*10^-3=x times larger than 4*10^-4
4*10^-3=x*4*10^-4
divide both sides by 4
10^-3=x*10^-4
divide both sides by 10^-4
10^1=x
10^1=10
answer is 10 times or C
