Final Answer :
B
Explanation :
First, distribute the innermost parentheses: 2[9y−3+21y2−7y+7]2[9y - 3 + 21y^2 - 7y + 7]2[9y3+21y27y+7] . Combine like terms inside the brackets to get 2[21y2+2y+4]2[21y^2 + 2y + 4]2[21y2+2y+4] . Then distribute the 2 across the terms inside the brackets to get 42y2+4y+842y^2 + 4y + 842y2+4y+8 .
