# 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
