(By+by+1) -
A wooden beam is (by? +by+1) meters long. If a piece of length (y2 - 11) meters is cut off, express the length of the
remaining piece of beam as a polynomial in y.

Answer 1

Beam = 6y^2 + 6y + 1
Cut off = y^2 -11
Remaining = Beam - Cutoff
Rem = 6y^2 + 6y + 1 - (y^2 -11)
REM = 5y^2 +6y + 12

Answer 2

remaining length: 5y² + 6y + 12

Step-by-step explanation:

new length = original length - length cut

solve for new length:

6y² + 6y + 1 - (y² - 11)

6y² + 6y + 1 - y² + 11

6y² - y² + 6y + 11 + 1

5y² + 6y + 12
