Solve the following equation by factoring: 9x^2 – 3x – 2 = 0
Answer choices:
A. x=-1/3 or x=2/3
B. x=-2/3 or x=1/3
C. x=-2/3 or x=-1/3
D. x=1/3 or x=2/3

A

Step-by-step explanation:

Given

9x² - 3x - 2 = 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 = 9 × - 2 = - 18 and sum = - 3

The factors are - 6 and + 3

Use these factors to split the x- term

9x² - 6x + 3x - 2 = 0 ( factor the first/second and third/fourth terms )

3x(3x - 2) + 1(3x - 2) ← factor out (3x - 2) from each term

(3x - 2)(3x + 1) = 0

Equate each factor to zero and solve for x

3x - 2 = 0 ⇒ 3x = 2 ⇒ x =

3x + 1 = 0 ⇒ 3x = - 1 ⇒ x = -

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
