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

Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You need to apply the Distributive property on the left member of the equation:

2. Now, you must solve for
, as following:

Answer:
0.1961
Step-by-step explanation:
Since these two probabilities are independent of each other, we can simply multiply them.
The probability that a voter will support the Democratic candidate for governor is 0.53.
The probability that a voter will support the Democratic candidate for attorney general is 0.37.
This makes the probability that a voter supports both Democratic candidates 0.53(0.37) = 0.1961.
