Answer:
x = - , x =
Step-by-step explanation:
Given
6x² + x - 1 = 0
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 6 × - 1 = - 6 and sum = + 1
The factors are - 2 and + 3
Use these factors to split the x- term
6x² - 2x + 3x - 1 = 0 ( factor the first/second and third/fourth terms )
2x(3x - 1) + 1(3x - 1) = 0 ← factor out (3x - 1) from each term
(3x - 1)(2x + 1) = 0
Equate each factor to zero and solve for x
2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = -
3x - 1 = 0 ⇒ 3x = 1 ⇒ x =

Answer:
The correct option is 1.
Step-by-step explanation:
it is given that the probability of a randomly selected point on the grid below is in the blue area is 9/16.
In the given grid we have only two colors that are blue and white.
Let A be the event of a randomly selected point on the given grid is in the blue area.
If the randomly selected point on the given grid does not lie in the blue area, it means it lies on white area.
We will calculate P(A'), to find the probability that a randomly selected point is in the white on the grid.
We know that the sum of the probability is 1.
It is given that
Therefore option 1 is correct.
