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 = - 
<span> For this case we have the following number:
710200
We are going to decompose this number as the sum of three numbers:
</span>
<span> Let's now write each number:
70000: seven hundred thousand
10000: ten thousand
200: two hundred
Therefore, the complete expression is:
Seven hundred ten thousand two hundred
Answer: Seven hundred ten thousand two hundred</span>
