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 (5a−8)+(2a2+2a−1)=2a2+7a−9 Correct – 5a-8+(2a2+2a-1)=2a2+7a-9 Incorrect – 5a-8+(2a2+2a-1)=2a2+7a-9 (b2+6b−4)−(3b+b2)=2b2+3b−4 Correct – (b2+6b-4)-(3b+b2)=2b2+3b-4 Incorrect – (b2+6b-4)-(3b+b2)=2b2+3b-4 (9c−4c2)−(2c2+c)=−6c2+10c Correct – (9c-4c2)-(2c2+c)=-6c2+10c Incorrect – (9c-4c2)-(2c2+c)=-6c2+10c
