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. x = 0 and x = -2 You can factor x^2 + 2x = 0 as: x (x + 2) = 0 Now, we can solve each term for 0: x = 0 - no other work needed, and x + 2 = 0 x + 2 -2 = 0 - 2 x + 0 = -2 x = -2. Factor by grouping. u2 − u−2 = 0 u 2 - u - 2 = 0. x = 0 x = 0. Find the properties of the given parabola. Tap for more steps x(x2 − 3x+2) = 0 x ( x 2 - 3 x + 2) = 0. Solve Using the Quadratic Formula x^2+2x-13=0. 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. x(2x − 1) = 0. x = 0 x = 0. x2 + 2x − 22 = 0 x 2 + 2 x - 22 = 0. −b±√b2 −4(ac) 2a - b ± b 2 - 4 ( a c) 2 a. x = 0 x = 0 Solve an equation, inequality or a system. Rewrite 22x 2 2 x as (2x)2 ( 2 x) 2. x−1 = 0 x - 1 = 0. Factor x2 + 2x−63 x 2 + 2 x - 63 using the AC method. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. Integration.838 x = (2+√292)/18= (1+√ 73 )/9= 1. x^2 + 2x + (1/22)^2 +1 = 0. Related Symbolab blog posts. Add 1 to both sides of the equation : On the right hand side we have : Solve Using the Quadratic Formula x^2-2x=0. (x+1)^2 + 1 = 0. 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. Related Symbolab blog posts. We also learn that a^2 + b^2 = (a+b) (a-b), so in this case: (x+1)^2 + 1^2 = 0.
