Which of the following is a factor of 7x2 - 12x - 4? (6 points)
grin007 [14]

Answer:

We conclude that 'None of the above' is the correct answer.                    

Step-by-step explanation:

Given the expression

7x^2\:-\:12x\:-\:4

Breaking the expression into groups

7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)

Factor out x from 7x^2\:+\:2x

=x\left(7x+2\right)

Factor out -2 from \left(-14x-4\right)

=-2\left(7x+2\right)

so the expression becomes

7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)

                         =x\left(7x+2\right)-2\left(7x+2\right)

Factor out the common term 7x+2

                         =\left(7x+2\right)\left(x-2\right)

Therefore, from the given options, we conclude that 'None of the above' is the correct answer.
