Question

determine the difference. write your answer in standard form.
$(-0.7y + 2.3) - (-0.1y + 1.5y^2 + 0.8)$

Explanation:

Step1: Distribute the negative sign

$(-0.7y + 2.3) + 0.1y - 1.5y^2 - 0.8$

Step2: Rearrange terms by degree

$-1.5y^2 -0.7y +0.1y +2.3 -0.8$

Step3: Combine like terms

$-1.5y^2 + (-0.7+0.1)y + (2.3-0.8)$

Step4: Simplify coefficients

$-1.5y^2 -0.6y + 1.5$

Answer:

$-1.5y^2 -0.6y + 1.5$
