Answer:
x²-9x+14=0
Step-by-step explanation:
We can use Vieta's formula:
x²-(sum of roots)x+(product of roots)=0
x²-(2+7)x+(2×7)=0
7/12.
The favourable outcomes are (1,6), (2,5), (2,6), (3,4), (3,5), (3,6) (4,5), (4,6) (5,6),
(6,1), (5,2) (6,2) (4,3) (5,3) (5,4) (6,3) (6,4) (6,5) (4,4) (5,5) (6,6)
= 21.
Total number of possible outcomes = 6*6 = 36.
So it's 21/36
= 7/12.
4x^2 - 1 = 0
x = 1/2, x = -1/2
2x = 1, 2x = - 1
2x - 1 = 0, 2x + 1 = 0
( 2x - 1 )( 2x + 1 ) = 0
I think the answer is a=-1/21
