Answer 2

same as previous , can you tell me such two numbers whose product is -18 & sum is 10 ?

Answer 3

x^2 and 10x?

Answer 4

x^2+9x+2x-18... solve now...

Answer 5

no , that is such a & b , a * b = -18 & a + b = 10
So we can not find such numbers so it is also prime ...

Answer 6

Ok, So it's A?

Yup ...
