Integral of x^2/((x 1)(x 2)(x 3)) dx YouTube
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.
(x+2)(x+3) Expand and Simplify YouTube
To solve the equation for different variables step-by-step clear any fractions by multiplying both sides of the equation by the LCM of the denominators. Get all the terms with the wanted variable on one side of the equation and all the other terms on the other side. Isolate the variable, and solve for the variable by undoing any arithmetic.

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.

The solution (s) to a quadratic equation can be calculated using the Quadratic Formula: The "ยฑ" 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.
