Question

How do you determine the value of k so that 4x2+24x+k=0 has discriminant zero?

Answer 1

Answer:

k = 36

Step-by-step explanation:

a=4   b= 24    c= 0

discriminant  = 0

b^2 -4ac = 0

b^2 = 4ac

24x24 =4x4xk

k = 24x24/[4x4]

     = 6x6

    =36

Answer 2

$<font color = "blue"><marquee>A = 4 B = 24 C = K</font color="blue"></marquee>$

b² - 4ac

= (24)² - 4×4×k

= 576 - 16k

= k = 576/16

= 36
