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
Answer:
? = 1 (assuming right-angled triangle)
Step-by-step explanation:
This is an application of Pythagoras' Theorem, but rearranged:
is, of course, 10, so 10 - 9 = 1, and 
.
