Question

what tis the prodct 3 x 4

Answer 1

in what way are you asked to describe the solution.... by using the discriminant...?

Answer 2

@campbell_st

Answer 3

You can solve for x, and then comment on the values obtained.

Answer 4

well the discriminant is
\[\Delta = b^2 - 4ac\]

you have a = 9, b = -6 and c = 5

substitute and calculate an answer

then the type of roots can be

\[\Delta > 0\] real unequal roots, if the value is a square number the roots are real and rational, if not a square number real and irrational

\[\Delta = 0\] the quadratic is a perfect square and so the roots real and equal.

\[\Delta < 0\] the roots are complex.

hope it helps
