May 4, 2018 · The graphic of the function x|->4x^3-6x is symmetric with respect to the origin of the axes system. Let the graphic of our function be Psi_f with f(x) = 4x^3-6x, f:RR->RR. There are two …

f (x) has zeros +-sqrt (5) and -2 Given: f (x) = 3x^3+6x^2-15x-30 Note that all of the terms are divisible by 3. In addition, the ratio of the first and second terms is the same as that of the third and fourth terms.

We're dividing a single term, #6x^3#, into a polynomial, so we can take advantage of the following fact which allows us to effectively divide one term into other terms:

Jan 29, 2017 · 6x^2+x-1 = (2x+1) (3x-1) Here are a couple of methods (in no particular order): Method 1 Note that: (ax+1) (bx-1) = abx^2+ (b-a)x-1 Comparing with: 6x^2+x-1 we want to find a, b such that …

Progress the resulting equation to determine the x-intercepts color (brown) ("Option 3:") Factorise the equation and thus determine x-intercepts. x_ ("vertex")" is " 1/2 way between. …

Explanation: As you are using # f (x) # I am assuming you are at a higher level of Mathematics.

The factored version is (x+3)^2 Here's how I approached it: I can see that x is in the first two terms of the quadratic, so when I factor it down it looks like: (x+a)(x+b) And when that gets expanded it looks like: …

Aug 1, 2015 · Explanation: In order to solve this quadratic equation by completing the square, you need to write the left side of the equation as the square of a binomial.

How do you use the important points to sketch the graph of y = x2 − 6x + 1? Algebra Quadratic Equations and Functions Quadratic Functions and Their Graphs

Explanation: First, subtract #color (red) (4)# and #color (blue) (6x)# from each side of the equation to isolate the #x# term while keeping the equation balanced:
