Which of the following is the correct factored form of the given equation?

x 2 + 3x - 4 = 0

a. (x - 1)(x + 4) = 0
b. (x - 1)(x - 4) = 0
c. (x + 1)(x - 4) = 0

A.

Step-by-step explanation:

Given equation :

We can rewrite the above equation as :

Which can be rewritten as :

i.e.

Take x common from first two terms and 4 from last two terms , we get

Take (x-1) common from both terms , we get

Thus, the correct factored form of the given equation :

A.

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

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
