Question

$x^2-2x+1$ is a polynomial in which variable:

Answer 1

Answer:

find your answer

Step-by-step explanation:

polynomial can have:

constants (like 3, −20, or ½)

variables (like x and y)

exponents (like the 2 in y2), but only 0, 1, 2, 3, ... etc are allowed

that can be combined using addition, subtraction, multiplication and division ...

... except ...

... not division by a variable (so something like 2/x is right out)

so the given one is not a polynomial

Answer 2

Step-by-step explanation:

x2 + 2ax, one has to add a2.] ... Solve the equation sqrt(x+2) + 2 = 2x. ... two polynomial equation (
