![]() ![]() Since (h, k) is the vertex, you will just have to solve the equation for 'a' by changing f (x) and x into the coordinates of the point. To factor a difference of cubes, find a and b and plug them into (a. The standard form of quadratic functions is f (x) a (x - h) 2 + k. We can do the same to expand an expression with a sum and a difference, such as \((x+5)(x-2)\), or to expand an expression with two differences, for example, \((x-4)(x-1)\). Similarly, the factored form of 125x3 -27圓 (a 5x, b 3y) is (5x - 3y)(25x2 +15xy + 9y2). In a previous lesson we saw how to use a diagram and to apply the distributive property to multiply two linear expressions, such as \((x+3)(x+2)\). Factor calculator finds all factors and factor pairs of any positive non-zero integer. Consider the factor form of binomial 3x2. Factoring calculator to find the factors or divisors of a number. When the quadratic expression is a product of two factors where each one is a linear expression, this is called the factored form.Īn expression in factored form can be rewritten in standard form by expanding it, which means multiplying out the factors. The process of expressing a given number or algebraic expression as the product of its factors is called factoring. The function \(f\) can also be defined by the equivalent expression \((x+2)(x+1)\). We refer to \(a\) as the coefficient of the squared term \(x^2\), \(b\) as the coefficient of the linear term \(x\), and \(c\) as the constant term. Learn any part of your course with video lessons, study guides, exam-like practice, and live review for Pre-Calculus 11 at British Columbia High School. The Factoring Calculator transforms complex expressions into a product of simpler factors. In general, standard form is \(\displaystyle ax^2 + bx + c\) Factoring Calculator Step 1: Enter the expression you want to factor in the editor. The quadratic expression \(x^2 + 3x + 2\) is called the standard form, the sum of a multiple of \(x^2\) and a linear expression ( \(3x+2\) in this case). Factored Form Main Concept Quadratic functions can be written in three forms. ![]() ![]() For example, a quadratic function \(f\) might be defined by \(f(x) = x^2 + 3x + 2\). A quadratic function can often be represented by many equivalent expressions. ![]()
