Answer:
1.)no real solution/no real roots
2.) -19
3.) 0
4.)40
5.)-8
Step-by-step explanation:
pa follow na Lang or pathanks
1. x² - 48
2. -19
3. 0
4. 160
5. -8
(b² - 4ac) = discriminant formula
1. a = 6; b = x; c = 2
x² - 4(6)(2)
= x² - 48
2. a = 1; b = -3; c = 7
-3² - 4(1)(7)
9 - 28
= -19
3. a = 1; b = 8; c = 16
8² - 4(1)(16)
64 - 64
= 0
4. a = 3; b = 8; c = -8
8² - 4(3)(-8)
64 + 96
= 160
5. a = 3; b = -4; c= 2
-4² - 4(3)(2)
16 - 24
= -8
