Step 2. Substitute the values a = 1 a = 1, b = −2 b = - 2, and c = −1 c = - 1 into the quadratic formula and solve for x x. (b 2)2 = (1)2 ( b 2) 2 = ( 1) 2. Tap for more steps x(x−1) = 0 x ( x - 1) = 0. Answer link. If any individual factor on the left side of the equation is equal to 0 0, the entire expression will be equal to 0 0. Rewrite the equation in vertex form. Step 1. Add 1 to both sides of the equation : On the right hand side we have : Solve Using the Quadratic Formula x^2-2x=0. Two numbers r and s sum up to 2 exactly when the average of the two numbers is \frac{1}{2}*2 = 1. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. x2 − 2x − 24 = 0 x 2 - 2 x - 24 = 0. x + 0 = − 2. 2±√(−2)2 −4 ⋅(1⋅−2) 2⋅1 Simplify. x3 − x2 − 2x = 0 x 3 - x 2 - 2 x = 0. (b 2)2 = (1)2 ( b 2) 2 = ( 1) 2. If any individual factor on the left side of the equation is equal to 0 0, the entire expression will be equal to 0 0. Use the quadratic formula to find the solutions. Two numbers r and s sum up to \frac{1}{3} exactly when the average of the two numbers is \frac{1}{2}*\frac{1}{3} = \frac{1}{6}. r + s = 2 rs = 1. View Solution.500 x = 1 Step by step solution : Step 1 :Equation at the end of step 1 : (22x2 - 2x) - 2 = 0 Step 2 : Step 3 :Pulling out like terms 4x2-2x-3=0 Two solutions were found : x = (2-√ Solve Using the Square Root Property x^2-2x-20=0. Substitute the values a = 1 a = 1, b = −2 b = - 2, and c = −4 c = - 4 into the quadratic formula and solve for x x. Step 5.4. Use the quadratic formula to find the solutions. Substitute the values a = 1 a = 1, b = −2 b = - 2, and c = −5 c = - 5 into the quadratic formula and solve for x x.
