<h3>What is a polynomial function?</h3>

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.

2x² + 7x +3 = 0
2x² + 6x + x + 3 = 0
2x (x+3) + 1(x + 3) = 0
(2x + 1)(x + 3) = 0
2x+ 1 = 0  ;  x + 3 = 0
x = -1 / 2 ;  x  = -3

Thus, the values of the x that satisfies the equation 2x² + 7x +3 = 0  is -1/2 and -3 .
