Microsoft showed off a new Surface 2-in-1 at its big Surface event called the Surface Pro X. It packs a new system on a chip developed between Microsoft and Qualcomm. It has high performance, particularly in A.I. tasks, with a very low powe

We shall now solve each term = 0 separately In other words, we are going to solve as many equations as there are terms in the product Jan 05, 2016 · 3x(x - 4) In a case like this where there are only two terms, you can start by just taking out the common factor, which in this case is 3x. 3x^2 - 12x = 3x(x - 4) If the complete expression is 3x^2 - 12x = 0 then eitherx=0 or x=4 Jun 03, 2018 · The roots are -1,-1,2 It is easy to see by inspection that x = -1 satisfies the equation : (-1)^3-3times(-1)-2 = -1+3-2=0 To find the other roots let us rewrite x^3-3x-2 keeping in mind that x+1 is a factor: x^3-3x-2 = x^3+x^2-x^2-x-2x-2 qquadqquad = x^2(x+1)-x(x+1)-2(x+1) qquadqquad = (x+1)(x^2-x-2) qquadqquad = (x+1)(x^2+x-2x-2) qquadqquad = (x+1){x(x+1)-2(x+1)} qquadqquad = (x+1)^2(x-2 In mathematics, trigonometric substitution is the substitution of trigonometric functions for other expressions. In calculus, trigonometric substitution is a technique for evaluating integrals. 5.2 Factoring 4x 2 - 3x + 5 The first term is, 4x 2 its coefficient is 4 . The middle term is, -3x its coefficient is -3 . The last term, "the constant", is +5 Step-1 : Multiply the coefficient of the first term by the constant 4 • 5 = 20 Step-2 : Find two factors of 20 whose sum equals the coefficient of the middle term, which is -3 .

Combine 4x and -3x to get x. x-x=0 . Subtract x from both sides.

Ответ: 3*x-x^2=0. x*(3-x)=0. x=0 ; x=3. Источник: http://znanija.com/task/143236. 2 вариант решения: (3x-x-2)=0 Ответ: Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. Rozwiązanie: Krok 1. Obliczenie miejsc zerowych wielomianu. Taką nierówność jak każdą inną tego typu możemy rozwiąz Quadratic. This is easily seen by distributing $3x$ to $(x-2)$ We are left with $y = 3x^2 - 6x$ which clearly follows as a quadratic.
