Find the value of 'k' for which the
quadratic equation has equal roots:
K (y - 2)+6 = 0*​

Answer 1

Answer:

Give reasons why following sentences

are right or wrong:

(1) The main aim of distributional

maps is to show location.

(2) In choropleth maps, only one

population distribution.

(6) In dot method, every dot should

have an appropriate scale.

(7) Isopleth maps are not made using

Answer 2

Answer:

k(y−2)+6=0

k

2

−2k+6=0

Since the roots are equal,

⇒b 2=4ac

(−2k) 2=4(k)(6)

4k 2=4k(6)

∴k=6
