Given $$x^2=5x-9$$   

Label the values

How do you find the discriminant?

If the discriminant is positive, then the solution will be

If the discriminant is negative, then the solution will be

Determine the value of the discriminant

x² + 7x + 13=0

For the function below, what is the discriminant?

___________

x² + 8x + 16 = 0

What all must occur BEFORE you can use the Quadratic Formula? Check ALL that apply.

Solve using the quadratic formula :

x² - 7x + 12 = 0

Use the quadratic formula to find the solutions for

y = -x² - 5x + 12

$$3x^2-10x+1=0$$  

Solve using the quadratic formula.

$$2x^2=8x+3$$

Step 1: $$2x^2-8x-3=0$$  

Step 2: $$x=\frac{8\pm\sqrt{64-4\left(2\right)\left(-3\right)}}{4}$$  

Step 3: $$x=\frac{8\pm\sqrt{40}}{4}$$

Step 4: $$x=\frac{8\pm2\sqrt{10}}{4}$$  

Step 5: $$x=\frac{4\pm\sqrt{10}}{2}$$
