The total area, in square inches, of a picture in a picture frame is calculated by the expression of

50x^2 + 150x + 100 where x
is the width of the picture frame. Which of the following are factors of 50x^2 + 150x + 100
?

Answer 1

(10x + 10)

Explanation:

50x^2 + 150 x + 100

= 50 (x + 1) (x + 2)

= 5 (10x + 10) (x + 2)

So the answer is (10x + 10)
