Question

Expand.
If necessary, combine like terms.
(2x + 5)(x – 5) =

Answer 1

To Expand: (2x + 5)(x - 5).

(2x + 5)(x - 5)

= 2x(x - 5) + 5(x - 5)

= 2x² - 10x + 5x - 25

= 2x² - 5x - 25 Ans.

(Combined the like terms)

Answer 2

2x² - 5x - 25

Explanation:

Use FOIL method

(2x + 5)(x - 5) = 2x*x + 2x*[-5] + 5*x + 5*[-5]

= 2x² -10x + 5x - 25 {add like terms}

= 2x² - 5x - 25
