Parabola, Finding the Vertex : 4.1 Find the Vertex of y = 3x 2-x-2 Parabolas have a highest or a lowest point called the Vertex . Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history Add '2.25' to each side of the equation. -3x + 2.25 + x 2 = 2 + 2.25 Reorder the terms: 2.25 + -3x + x 2 = 2 + 2.25 Combine like terms: 2 + 2.25 = 4.25 2.25 + -3x + x 2 = 4.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 4.25 Calculate the square root of the right side: 2.061552813 Break this problem into two subproblems by 3 × x × 2 × x = So now you can multiply what are the same.

x^ {2}-3x-28=0. x2 − 3x − 28 = 0. To solve the equation, factor x^ {2}-3x-28 using formula x^ {2}+\left (a+b\right)x+ab=\left (x+a\right)\left (x+b\right). To find a and b, set up a system to be solved. To simplify your expression using the Simplify Calculator, type in your expression like 2(5x+4)-3x. The simplify calculator will then show you the steps to help you learn how to simplify your algebraic expression on your own.

For example, enter 3x+2=14 into the text box to get a step-by-step explanation of how to solve 3x+2=14. 3x • (x - 2) = 0 Step 2 : Theory - Roots of a product : 2.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. 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 For multiplication, use the * symbol.

x2+3x+2=0 Two solutions were found : x = -1 x = -2 Step by step solution : Step 1 :Trying to factor by splitting the middle term 1.1 Factoring x2+3x+2 The first term is, x2 its For multiplication, use the * symbol. A * symbol is not necessary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5).
