Question

Find the value of k so that the equation 4x^2 + 4x + k has equal root​

Answer 1

Answer:

Step-by-step explanation:

for equal roots

b^2-4ac

4^2-4(4k)=0

=16-16k=0

16k=16

k=1

Answer 2

Answer:

k = -24

Step-by-step explanation:

4x^2+4x+k=0

4(2)^2+4×(2)+k=0

4×4+4×2+k=0

16+8+k=0

24+k=0

k=-24
