Find the value of c that completes the square. k^2-18k+c
2 answers:
Answer:
c = 81
(k-9)(k-9)
k²-18k +81
Answer:
Discriminant(D) = 0
Therefore b² = 4ac
when b = -18, a = 1, c = c
puting the values in the equation...
(-18)² = 4(1) x C
324 = 4C
divide though by 4
we have : C = 324/4
C = 81

multiply both sides by 2 to get
2A = (a+b)*h
divide both sides by h
to get 2A/h = a+b
subtract b from both sides to get a = 2A/h -b
