  • Solve Using the Quadratic Formula x^2-2x-9=0 - Mathway
    Use the quadratic formula to find the solutions −b±√b2 −4(ac) 2a - b ± b 2 - 4 (a c) 2 a Substitute the values a = 1 a = 1, b = −2 b = - 2, and c = −9 c = - 9 into the quadratic formula and solve for x x 2±√(−2)2 −4 ⋅(1⋅−9) 2⋅1 2 ± (- 2) 2 - 4 ⋅ (1 ⋅ - 9) 2 ⋅ 1 Simplify Tap for more steps The result can be shown in multiple forms
  • Solve x^2-2x-9=0 | Microsoft Math Solver
    x=\frac{-\left(-2\right)±\sqrt{\left(-2\right)^{2}-4\left(-9\right)}}{2} This equation is in standard form: ax^{2}+bx+c=0 Substitute 1 for a, -2 for b, and -9 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}
  • Solve Quadratic equations x2-x-9=0 Tiger Algebra Solver
    (1): "x2" was replaced by "x^2" The first term is, x2 its coefficient is 1 The middle term is, -x its coefficient is -1 Step-2 : Find two factors of -9 whose sum equals the coefficient of the middle term, which is -1 Observation : No two such factors can be found !! x2 - x - 9 = 0
  • [FREE] x^2 - 2x - 9 = 0 One solution to the given equation can be . . .
    To solve the equation x² - 2x - 9 = 0, we can use the quadratic formula: x = (-b ± √(b² - 4ac)) (2a) Comparing the given equation with ax² + bx + c = 0, we have a = 1, b = -2, and c = -9 Substituting these values into the quadratic formula, we get: x = (2 ± √((-2)² - 4(1)(-9))) (2(1))
  • Solve quadratic equation x^2-9 = 0 - Math Portal
    Solve x2 − 9 = 0 using factoring First we need to factor trinomial x2 − 9 and than we use factored form to solve an equation x2 − 9 = 0 We can see that both terms are perfect squares x2 = (1x)2 and 9 = 32 so we can use the difference of squares formula: Step 1: Set each factor to zero and solve equations Isolate the squared variable term:
  • Solve by Factoring x^2-9=0 | Mathway
    Since both terms are perfect squares, factor using the difference of squares formula, a2 −b2 = (a+b)(a−b) a 2 - b 2 = (a + b) (a - b) where a = x a = x and b = 3 b = 3 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 Set x+3 x + 3 equal to 0 0 and solve for x x

    Tiger shows you, step by step, how to solve YOUR Quadratic Equations (x-2)^2-9=0 by Completing the Square, Quadratic formula or, whenever possible, by Factoring
  • Solve x^2-9x=0 | Microsoft Math Solver
    All equations of the form ax^ {2}+bx+c=0 can be solved using the quadratic formula: \frac {-b±\sqrt {b^ {2}-4ac}} {2a} The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction This equation is in standard form: ax^ {2}+bx+c=0
  • Solve Using the Quadratic Formula x^2-9=0 - Mathway
    Substitute the values a = 1 a = 1, b = 0 b = 0, and c = −9 c = - 9 into the quadratic formula and solve for x x 0±√02 −4⋅(1 ⋅−9) 2⋅1 0 ± 0 2 - 4 ⋅ (1 ⋅ - 9) 2 ⋅ 1 Simplify Tap for more steps The final answer is the combination of both solutions
