17. x^2 + 2x + 1
valentina_108 [34]

Answer:

E. This polynomial could be factored by using grouping or the perfect squares methods.

Step-by-step explanation:

x^2 + 2x + 1

There is no greatest common factor

This is a perfect square

a^2 + 2ab+ b^2 = ( x+1)^2

We can factor this  by grouping

x^2 + 2x + 1

(x^2 +x) + (x+1)

x( x+1)  + x+1

Factor out x+1

( x+1)  ( x+1)

This is not the difference of squares since there is no subtraction

The area of a rectangle is 10r (squared) − 11r − 6. The width is 2r − 3. What is the length?
sladkih [1.3K]
<span>10r^2 − 11r − 6 = (2r - 3)(5r +2)
so
A = </span>(2r - 3)(5r +2)<span>
as you know A =  L * W
if width = </span>(2r - 3) then length = (5r +2)

answer
length = (5r +2)
