Find the value of k for which the quadratic equation 4x2+kx+3=0 has equal roots.

k = +/-√48

Step-by-step explanation:

4x^2 + kx + 3 = 0

For equal (duplicate) roots the discriminant = 0, so

k^2 - 4*4*3 = 0

k^2 - 48 = 0

k^2 = 48

k = +/-√48

answer: 32.68

step-by-step explanation:

x=2

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
