i think i am going to fail algebra class this year... My grades are very bad :(
Now that you understand, give me an example.
A polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
Find the roots of the polynomial equation 5x2 - 7x + 2 = 0
5x(x - 1) - 2(x - 1) = 0
5x2 - 5x - 2x + 2 = 0
Either 5x - 2 = 0 or x - 1 = 0
5x2 - 7x + 2 = 0
(5x - 2)(x - 1) = 0
Good work, keep it up!
Hence, the roots of the given polynomial equation are 1, 2/5.
