Select one of the factors of 5x² + 7x + 2.
(5x - 2), (x + 2), (5x + 1), None of the above

Solution:

Given: Quadratic polynomial is 5x² + 7x + 2

Factorizing the quadratic polynomial by splitting the middle terms, we get

5x² + 7x + 2

=5x² + 5x + 2x + 2

= 5x(x + 1) + 2(x + 1)

=(5x + 2)(x + 1) are the factors of 5x² + 7x + 2.

Select one of the factors of 5x² + 7x + 2.

Summary:

The factors of the quadratic equation 5x² + 7x + 2 are (5x + 2)(x + 1).
