14x^2y+4x-7xy-2=(2x-1)

(2x -1)  (7xy+2)

Step-by-step explanation:

Rewrite the equation as follows:

(14x^2y - 7xy)   +  (4x -2)

Factor 7xy from the first term and 2 from the second term:

7xy(2x -1 ) + 2 ( 2x -1)

Factor (2x-1) from each term to get

(2x -1) ( 7xy + 2)

You can multiply this out to verify the answer.

the line of

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
