There are various steps followed in product development. briefly list the steps and provide explanations.

Product development refers to introduction of new product or enhancement of some existing product.

Explanation: It has following steps :-

1. Idea generation : It refers to marketing research and collection of different ideas and opinions.

2. Idea screening : It refers to analyzing those ideas.

3. Concept testing : It refers to analyzing the feedback from a sample of customers.

4. Business analysis : Evaluating whether the product will be profitable or not

5. Product development : Initiation of product introduction.

6. Test marketing : Introduction of product at a small stage

7. commercialization : Introducing product at a large level if the testing as successful.

8. Review of market performance : Monitoring the performance of product in the market.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor 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 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7
