Shauna solved the polynomial equations given in the table. Determine whether each polynomial is correct. Select Correct or Incorrect for each equation. Equation Correct Incorrect (5aβˆ’8)+(2a2+2aβˆ’1)=2a2+7aβˆ’9 Correct – 5a-8+(2a2+2a-1)=2a2+7a-9 Incorrect – 5a-8+(2a2+2a-1)=2a2+7a-9 (b2+6bβˆ’4)βˆ’(3b+b2)=2b2+3bβˆ’4 Correct – (b2+6b-4)-(3b+b2)=2b2+3b-4 Incorrect – (b2+6b-4)-(3b+b2)=2b2+3b-4 (9cβˆ’4c2)βˆ’(2c2+c)=βˆ’6c2+10c Correct – (9c-4c2)-(2c2+c)=-6c2+10c Incorrect – (9c-4c2)-(2c2+c)=-6c2+10c
