Answer:

remaining length: 5y² + 6y + 12

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
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
