Question

simplify the expression.
$6.7y^2 + 9.4 + 4y - 5.8 - 2y + y^2$
$6.7y^2 + 9.4 + 4y - 5.8 - 2y + y^2 = \square$
(use the operation symbols in the math pale

Explanation:

Step1: Combine like terms for \( y^2 \)

We have \( 6.7y^2 \) and \( y^2 \). Adding them together: \( 6.7y^2 + y^2 = (6.7 + 1)y^2 = 7.7y^2 \)

Step2: Combine like terms for \( y \)

We have \( 4y \) and \( -2y \). Adding them together: \( 4y - 2y = (4 - 2)y = 2y \)

Step3: Combine like terms for constants

We have \( 9.4 \) and \( -5.8 \). Adding them together: \( 9.4 - 5.8 = 3.6 \)

Step4: Combine all the simplified terms

Putting together the results from the previous steps: \( 7.7y^2 + 2y + 3.6 \)

Answer:

\( 7.7y^2 + 2y + 3.6 \)
