What is the answer to find the real solutions of the polynomial 2x^5+3x^4=18x+27
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

2x%5E5+%2B+3x%5E4 = 18x%2B27  --->  2x%5E5+%2B+3x%5E4 - %2818x%2B27%29  = 0  --->

x%5E4%2A%282x%2B3%29 - 9%2A%282x%2B3%29 = 0  --->  %28x%5E4-9%29%2A%282x%2B3%29 = 0  =====>


Real solutions are x = -3%2F2, sqrt%283%29, -sqrt%283%29.
