<h3>What is a polynomial?</h3>
Mathematical expressions called polynomials have one variable and many exponents.
The algebraic expression must have all of its exponents be non-negative integers in order for it to be a polynomial. As a general rule, an algebraic expression isn't a polynomial if it contains a radical.
No part of an algebraic expression should be - Variables' square roots. variable powers that are fractional. variable powers that are negative. variables in any fraction's denominator.
Exponents, variables, and constants make up a polynomial. The amount of terms a polynomial has determines its name.
Polynomials come in various varieties. Monomial, binomial, and trinomial, respectively.
The idea of the graph of a polynomial equation was first introduced by René Descartes in La géometrie, published in 1637.

<em>Answer:</em>
<em><u>X = 80</u></em>
<em>Step-by-step explanation:</em>
<em>Subtract </em><em>"5"</em><em> from both sides,</em>
<em>3x + 5 - 5 = 245 - 5</em>
<em><u>Simplify,</u></em>
<em>3x = 240</em>
<em><u>Divide both sides by </u></em><em><u>"3"</u></em><em><u>,</u></em>
<em>3x/3 = 240/3</em>
<em>X = </em><em>80</em>
