The variables a, b, and c represent polynomials where a = x + 1, b = x2 + 2x − 1, and c = 2x. what is ab + c in simplest form? x3 + 3x − 1 x3 + 4x − 1 x3 + 3x2 + 3x − 1 x3 + 2x2 − x + 1

If you would like to write a * b + c in simplest form, you can do this using the following steps:a = x + 1b = x^2 + 2x - 1c = 2xa * b + c = (x + 1) * (x^2 + 2x - 1) + 2x = x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x = x^3 + 3x^2 + 3x - 1The correct result would be x^3 + 3x^2 + 3x - 1.

Step-by-step explanation:

The answer is C. x3 + 2x2 - x + 1

Step-by-step explanation:

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
