Chapter 5: Q.361. (page 558)

Subtract $(8 y^{2} - y + 9)$ from $(11 y^{2} - 9 y - 5)$ .

Short Answer

Expert verified

The solution is $3 y^{2} - 8 y - 14$ .

Step by step solution

01

Step 1. Given information.

Subtract $(8 y^{2} - y + 9)$ from $(11 y^{2} - 9 y - 5)$ .

02

Step 2. Simplify the expression.

Solve it as follows:

$(11 y^{2} - 9 y - 5) - (8 y^{2} - y + 9) = 11 y^{2} - 8 y^{2} - 9 y + y - 5 - 9 (11 y^{2} - 9 y - 5) - (8 y^{2} - y + 9) = 3 y^{2} - 8 y - 14$

03

Step 3. Simplified answer.

Hence, the required simplified polynomial is $3 y^{2} - 8 y - 14$
