Question

 The discriminant of ax² -8x+3=0 is 16 then a =? ​

Answer 1

Answer:

a=4

Step-by-step explanation:

b2- 4ac= 16

64-12a= 16

so,

a=4

Answer 2

Step-by-step explanation:

comparing ax² - 8x + 3 = 0 with ax² +bx + c = 0

a = a , b = -8 , c = 3

formula : b² - 4ac = 16

16 = (-8)² - 4(a)(3)

16 = 64 - 12a

16 - 64 = -12a

-48 = -12a

-48/-12 = a

a = 4
