Question

resolva o produto notável (3x²+2y)²

Answer 1

$\LARGE\tt{}( {3x}^{2} + 2y)^{2} \\ \\ \LARGE\tt{}(3 {x}^{2} )^{2} + 2 \times { 3x}^{2} \times 2y + (2y) ^{2} \\ \LARGE\tt{} {9x}^{4} + 2 \times {3x}^{2} \times 2y + (2y)^{2} \\ \LARGE\tt{} {9x}^{4} + {12x}^{2} y + (2y) ^{2} \\ {\large\boxed{\boxed{  { \LARGE \tt {9x}^{4} + 12 {x}^{2} y + {4y}^{2} }}}}$

Bons estudos!
