Quadratic Equations Math
1x² - 6x + 8 = 0 Formula: -b ±√b² - 4ac
2a
a= 1 b= -6 c= 8
Step 1. X= -(-6) ±√-6² - 4(1)(8)
2(1)
Step 2. X= -(-6) ±√36 - 32
2
Step 3. X= +6±√4 ←change into a positive if the
2 number is negative.
Step 4. X= +6± 4 ←what is the square root of the
2 number that is beside the
Step 5. X= +6- 4 square root symbol.
2
Step 6. 10/2, 2/2 = 5, 1 Any of these are correct, as it
10 over 2 is then to be graphed.
