Answer:
Step-by-step explanation:
Step by step solution :
Step  1  :
Equation at the end of step  1  :
  7 +  3p2
Step  2  :
Polynomial Roots Calculator :
 2.1    Find roots (zeroes) of :       F(p) = 3p2+7
Polynomial Roots Calculator is a set of methods aimed at finding values of  p  for which   F(p)=0  
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  p  which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient
In this case, the Leading Coefficient is  3  and the Trailing Constant is  7.
 The factor(s) are:
of the Leading Coefficient :  1,3
 of the Trailing Constant :  1 ,7
3p2 + 7
