So far, so good; everyone learns this much in high school algebra. The way one usually goes about factoring quadratic polynomials is to make informed guesses for values of and and check whether their sum and product give the right coefficients. The key insight at this point, however, is that we don’t actually have to guess!.

With the quadratic formula: bring all terms to one side of the equation, leaving a zero on the other side. You can also use the quadratic formula for factoring trinomials.
It is an important process in algebra which is used to simplify expressions, simplify fractions, and solve equations. A “quadratic” is a polynomial that is written like “ax 2 + bx + c”, where “a”, “b”, and “c” are just numbers. For an easy case of factoring, you can identify the two numbers that will not only multiply to equal the constant term “c” but also add up to equal.

We're asked to solve for s and we have s squared minus 2 s minus 35 is equal to 0 now this is the first time that you've seen this type of what's essentially a quadratic equation you might be tempted to try to solve for s using traditional algebraic means but the best way to solve this especially when it's explicitly equal to 0 is to factor the left-hand side and then think about whether think.
To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask about factoring. Factor quadratic x^2-7x+12; expand polynomial (x-3)(x^3+5x-2) gcd of x^4+2x^3-9x^2+46x-16 with x^4-8x^3+25x^2-46x+16.
If the product of factors is equal to anything non-zero, then we can not make any claim about the values of the factors. Therefore, when solving quadratic equations by factoring, we must always have the equation in the form (quadratic expression) equals (zero) before we make any attempt to solve the quadratic equation by factoring.

The key to understanding factoring with quadratic equations is knowing that when the product of these two sets of parentheses is zero, at least one of the sets of parentheses must be equal to zero. Remember when we were graphing, we saw that the solution of our quadratic equation was the point (or points) at which the graph crossed the x-axis.
