Find the value of k so that the equation 3k2 + kx + 2 has equal roots |
|
Answer» Answer: 2√6 Step-by-step explanation: Here your equation is 3k^2+kx+2, and. it has equal roots... If it has equal roots then the value of d that is discriminant will be 0.... We know that d=b^2-4ac It can be written as b^2-4ac = 0
put the values... a=3, b=k, and c=2 therefore, k^2 - 4*3*2 = 0 k^2 - 24 = 0 and k^2 = 24 so, k will be √24 that can also be written as 2√6 so k=2√6... hope it helped you... stay blessed... |
