Question

Which of the following expressions is equivalent to $\frac{1}{2}{y}^2(6x+2y+12x-2y)$?

• A. $9x{y}^2$
• B. $18xy$
• C. $3x{y}^2+12x$
• D. $9x{y}^2-2y^3$
• E. $3x{y}^2+12x-y^3-2y$

Answer 1

The correct option is A $9x{y}^2$

Give expression $\frac{1}{2}{y}^2(6x+2y+12x-2y)⟹\frac{1}{2}{y}^2(18x+0y)⟹9x{y}^2$
