Question

Find the value of k so that the equation has equal roots 4x
2 + kx +9 =0.

Answer 1

Answer:The discriminent must equal zero for 2 real equal roots. That is, b^2 - 4ac =0, given ax^2 + bx + c = 0. Thus , k^2 - 4(9)(4) = 0……k is plus or minus 12

Step-by-step explanation:

Answer 2

Answer:

here' s ur answer dude

Step-by-step explanation:

Because its roots are real and equal hence its discriminate will should zero . hence , hence K = +12 or -12
