The solution (s) to a quadratic equation can be calculated using the Quadratic Formula: The "±" means we need to do a plus AND a minus, so there are normally TWO solutions ! The blue part ( b2 - 4ac) is called the "discriminant", because it can "discriminate" between the possible types of answer: when it is negative we get complex solutions.

Polynomial. In mathematics, a polynomial is a mathematical expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables. An example of a polynomial of a single indeterminate x is x² − 4x + 7. An example with three indeterminates.

Answer link. Use a variant of Pascal's triangle to find: (1+x+x^2)^3 = 1+3x+6x^2+7x^3+6x^4+3x^5+x^6 This is a power of a trinomial, not a binomial so the binomial theorem does not help much. However, note that 1, x, x^2 are in geometric progression, so we can use a variant of Pascal's triangle to find the coefficients we want.

Definite integral x 1 + x 2 + x 3 dx from 1 to 4 Teachoo
A second, slightly different way of approaching this is to consider the expression $$(1-x)(1 + x + x^2 + x^3 + \cdots)$$ Using the distributive property one gets $$(1 + x + x^2 + x^3 + \cdots) - (x + x^2 + x^3 + \cdots)$$ and again everything cancels except the $1$ in the first pair of parentheses, so $$(1-x)(1 + x + x^2 + x^3 + \cdots) = 1.
