What is the standard form of a polynomial #(5x - 2 + 3x^2) + (4x + 3)#?

Answer 1

#3x^2# + 9x + 1 = 0.

The “standard form” is an equation with each variable arranged in decreasing order of exponent and equated to zero. E.g. #x^2# + x + 1 = 0

In this case, we first must combine all of the terms: 9x + 1 + #3x^2# = 0. Then rearrange them into the “standard form”: #3x^2# + 9x + 1 = 0.

The standard form of the polynomial (5x - 2 + 3x^2) + (4x + 3) is:

3x^2 + (5x + 4x) - 2 + 3 = 3x^2 + 9x - 2 + 3 = 3x^2 + 9x + 1

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
