Question

Factorize 2x^2 - 7x - 39​

Answer 1

Answer:

(2x-13) (x+3)

Step-by-step explanation:

2x^2 -7x -39

we have to multiply 39 by 2 as per rule

(factors of 78 are 13 and 6)

2x^2 -7x -39

2x^2 -7x -39

now 2x^2 -7x -39

2x^2 +6x -13x -39

not by taking common

2x(x+3) -13(x+3)

so factors are..

(2x-13) (x+3)

now.

value of x is 13 and -3
