The required factor of 8x^2 − 4x − 84 is 4(x + 3)(2x − 7).
Factor of 8x^2 − 4x − 84 to be determine.
What is factors?
Factors can be define splitting the value in multipliable values.
Here,
[tex]=8x^2-4x- 84\\=4(2x^2-x-21)\\= 4(2x^2-7x+6x-21)\\= 4(x(2x-7)+3(2x-7))\\=4(x+3)(2x-7)[/tex]
Thus, the required factor of 8x^2 − 4x − 84 is 4(x + 3)(2x − 7).
