Question

And the other two options are A:108 and B: the equation has two real solutions.

Please help! thank u:)

Answer 1

The discriminant is zero which means there is 1 repeated real solution

Explanation:

9x^2 -12x +4 = 0

This is in the form

ax^2 +bx +c

a = 9 b=-12 c=4

The discriminant is

b^2 -4ac

(-12)^2 - 4(9)(4)

144 -144

0

The discriminant is zero which means there is 1 repeated real solution
