if two polynomial equations have real solutions , then will the equation that is the result of adding , subtracting or multiplying the two polynomial equation also have real solutions

multiplying is the right answer

Step-by-step explanation:

multiplying is not a problem, multiplying the two polynomial equations also has real solutions

adding or substracting does not work though

(1) has two real solutions

(2) has two real solutions

but (1) - (2) gives

= 0

this one has no real solution
