Factor out the greatest common factor. 28 x squared plus 8 x

4x(7x + 2)

Step-by-step explanation:

28x^2 + 8x =

= 2 * 2 * 7 * x * x + 2 * 2 * 2 * x

The common factors are shown above in bold. They are 2, 2, x.

2 * 2 * x = 4x. The greatest common factor is 4x. You factor 4x out of both terms.

= 4x(7x + 2)

4th option is correct xy=-10
