Question

simplify the following sum of polynomials completely.\\((10y^{2}-2y - 12)+(14y^{2}+14y + 15)\\)

Explanation:

Step1: Remove parentheses

$10y^2 - 2y - 12 + 14y^2 + 14y + 15$

Step2: Group like terms

$(10y^2 + 14y^2) + (-2y + 14y) + (-12 + 15)$

Step3: Combine like terms

$24y^2 + 12y + 3$

Answer:

$24y^2 + 12y + 3$
