Quadratic Formula Practice

a = 2 , b = 3, c = -5

a = 2, b = -3, c = 5

a = 2, b = -3, c = -5

a = -2, b = 3, c = 5

$$x=\frac{-2\pm\sqrt[\ ]{\left(2\right)^2-4\left(1\right)\left(-5\right)}}{2\left(1\right)}$$

$$x=\frac{2\pm\sqrt[\ ]{\left(2\right)^2-4\left(1\right)\left(-5\right)}}{2\left(1\right)}$$

$$x=\frac{-2\pm\sqrt[\ ]{\left(2\right)^2-4\left(1\right)\left(5\right)}}{2\left(1\right)}$$

$$x=\frac{3\pm\sqrt[\ ]{\left(-3\right)^2-4\left(2\right)\left(-5\right)}}{2\left(2\right)}$$

$$x=\frac{-3\pm\sqrt[\ ]{\left(-3\right)^2-4\left(2\right)\left(-5\right)}}{2\left(2\right)}$$

$$x=\frac{3\pm\sqrt[\ ]{\left(3\right)^2-4\left(2\right)\left(5\right)}}{2\left(2\right)}$$
