Question

Which of the following equations has only one solution?
x2 - 8x + 16 = 0
x(x - 1) = 8
x2 = 16

Answer 1

the first one has one solution of multiplicity 2

Answer 2

A,B,or C?

Answer 3

i do not see A,B, or C
i did say first one though

Answer 4

A.x2 - 8x + 16 = 0
B.x(x - 1) = 8
C.x2 = 16

Answer 5

A. has one solution

Answer 6

because b*(2) - 4ac = 0 and hence x_1,_2 = (8+/_ 0)/2 = 4
