Square Root Property

  1.  \rhd Solving quadratics using the square root property (2:18) Solve 2x^2 + 3 = 75 by isolating x^2 and applying the square root property.
  2. \rhd Solving quadratics by taking square roots (examples) (5:12) In this video we see how to solve the equation (x+3)^2 -4 = 0 and how to find the x-intercepts of the function f(x) = (x-2)^2 -9.
  3. \star Practice solving quadratics of the form (x+a)^2-b = 0
  4. \rhd Solving quadratics by taking the square root (strategy focusing on order of operations) (4:24) Solve 3(x+6)^2 = 75 paying special attention to the order of steps imposed by order of operations (PEMDAS).
  5. \rhd Solving quadratics by using the square root property (finding errors in steps!) (1:44) Finding and repairing errors in an attempted solution to 2(x+4)^2 = 242.
  6. \star Practice finding the mistake(s) in an attempted solution to a quadratic equation
