Subtract 1 from both side of the equation : x2+x = -1. Now the clever bit: Take the coefficient of x , which is 1 , divide by two, giving 1/2 , and finally square it giving 1/4. Add 1/4 to both sides of the equation : On the right hand side we have : x - 3 = 0 or x + I = 0 . So the solutions are x = 3. -1 . Mefhod: Quadratic formula. a = 1 , b = -2 . c ...

The blue part ( b2 - 4ac) is called the "discriminant", because it can "discriminate" between the possible types of answer: when it is negative we get complex solutions.Quote from the FAQ: "The difference is that 0:0.1:0.4 increments by a number very close to but not exactly 0.1", which is not the case, as the 0.3 is actually calculated 0.4-0.1, and not 0+0.1+0.1+0.1. This is in order to minimize accumulated errors.

Solving Equations Involving a Single Trigonometric Function. When we are given equations that involve only one of the six trigonometric functions, their solutions involve using algebraic techniques and the unit circle (see Figure 2).We need to make several considerations when the equation involves trigonometric functions other than sine and cosine.Quadratic equations x2 x 1 = 0 We think you wrote: This solution deals with quadratic equations. Overview Steps Terms and topics Related links Solution See steps Step by Step Solution Reformatting the input : Changes made to your input should not affect the solution: (1): "x2" was replaced by "x^2". Step by step solution :

2.1 Solve : (x-1)2 = 0. (x-1) 2 represents, in effect, a product of 2 terms which is equal to zero. For the product to be zero, at least one of these terms must be zero. Since all these terms are equal to each other, it actually means : x-1 = 0. Add 1 to both sides of the equation : x = 1. x=1/2 or x=-1 2x^2+x-1=0 Factorise. 2x^2+2x-x-1=0 2x(x+1)-1(x+1)=0 (2x-1)(x+1)=0 2x-1=0 or x+1=0 x=1/2 or x=-15x2+1=0 Two solutions were found : x= 0.0000 - 0.4472 i x= 0.0000 + 0.4472 i Step by step solution : Step 1 :Equation at the end of step 1 : 5x2 + 1 = 0 Step 2 :Polynomial Roots ... -x2+1=0 Two solutions were found : x = 1 x = -1 Step by step solution : Step 1 :Trying to factor as a Difference of Squares : 1.1 Factoring: 1-x2 Theory : A ...
