Solve the quadratic equation for x in the simplest equation -6x^2+15x+9=0

Mathematics
1 answer:
Alexus [3.1K]3 years ago
6 0

Answer:

x = 3, -1/2

Step-by-step explanation:

Use the quadratic formula:  x = [-b ± √b² - 4ac]/2a

The square root sign should be over the entire expression b² - 4ac

In this problem, a = -6, b = 15, and c = 9

So, putting in those values, we get x = -15 ± √225+216, all divided by -12

Simplifying further, we get -15 ± 21 all divided by -12, or -36/-12 = 3 OR

6/-12 = -1/2
