Question

2) In the quadratic equation a = 4 , b = - 8 ,c = 3. Find the values of

(i) + (ii) ​

Answer 1

Step-by-step explanation:

b^2-4ac

-8^2-4(4)(3)

=64-48

=16

X=-b+-√b^2-4ac/2a

X=-(-8)+-√16/2(4)

X=8+-√8/8

X=-1+-4

X=-5 or X=3

Answer 2

D= b²-4ac= -8² - 4×4×3 = 64- 48 =16

x= -b +- √D / 2a = 8 +- √16 / 8 = 8+-4/8

x= 12/8 = 3/2 and x= 4/8 = 1/2
