Question

Identify the number and type of solutions for the equation 9x² − 12x + 4 = 0.

A.) 1 nonreal complex

B.) 1 real

C.) 2 nonreal complex

D.) 2 real

Please give and only give the explanation and the solution.

Answer 1

The discriminate is ZER0.

It is a root of multiplicity 2, aka a double root.

It also can be factored (3x-2)(3x-2)=0

So x=2/3 is a double solution
