Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website! Start with the given expression. Take half of the coefficient to get . In other words, . Now square to get . In other words,where $ \( n_i(x) = \prod_{j=0}^{i-1}(x-x_j)\) $ The special feature of the Newton’s polynomial is that the coefficients \(a_i\) can be determined using a very simple mathematical procedure. For example, since the polynomial goes through each data points, therefore, for a data points \((x_i, y_i)\), we will have \(f(x_i) = y_i\), thus we havex=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=-1We would like to show you a description here but the site won’t allow us. x2+3x-1=0 Two solutions were found : x = (-3-√13)/2=-3.303 x = (-3+√13)/2= 0.303 Step by step solution : Step 1 :Trying to factor by splitting the middle term 1.1 Factoring x2+3x-1 ... 2x2+3x-1=0 Two solutions were found : x = (-3-√17)/4=-1.781 x = (-3+√17)/4= 0.281 Step by step solution : Step 1 :Equation at the end of step 1 : (2x2 ...

To answer the question of how the formulas for the volumes of different standard solids such as a sphere, a cone, or a cylinder are found, we want to demonstrate an example and find the volume of an ..., Question 166951: x^2-x-1=0 Solve by completing the square. Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website! Start with the given expression. Take half of the coefficient to get . In other words, . Now square to get . In other words,, Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step, The solution (s) to a quadratic equation can be calculated using the Quadratic Formula: The "±" means we need to do a plus AND a minus, so there are normally TWO solutions ! 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. , Two numbers r and s sum up to -2 exactly when the average of the two numbers is \frac{1}{2}*-2 = -1. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C. , 3.2 Solving x2-x-2 = 0 by Completing The Square . Add 2 to both side of the equation : x2-x = 2. 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 : 2 + 1/4 or, (2/1)+ (1/4), Solve by Factoring x^-2+x^-1-6=0. x−2 + x−1 − 6 = 0 x - 2 + x - 1 - 6 = 0. Factor x−2 +x−1 − 6 x - 2 + x - 1 - 6 using the AC method. Tap for more steps... (x−1 −2)(x−1 + 3) = 0 ( x - 1 - 2) ( x - 1 + 3) = 0. Rewrite the expression using the negative exponent rule b−n = 1 bn b - n = 1 b n., Click a picture with our app and get instant verified solutions.
