Solve each of the equation in Exercises 6 to 9:

Question

Philoid · Accepted Answer

We have,

This equation can be rewritten as follows:

9x² – 12x + 20 = 0

Now, in order to solve the equation we have to compare this with ax² + bx + c = 0 where a = 9, b = - 12 and c = 20

Thus, the discriminant of the above given equation is:

D = b² – 4ac

= (- 12)² – 4 × 9 × 20

= 144 – 720

= - 576

Hence, the required solutions are:

=
