Question

Cuanto es (5a²-6b²)²

Answer 1

lo resuelvas de la forma (a-b) ² = a²-2ab+b²

en este caso a = 5a² y b = 6b²

(5a²)²-2(5a²)(6b²)+(6b²)²

25a⁴ - 60a²b² + 36b⁴

Answer 2

$(5 {a}^{2} ) ^{2} - 2 \times 5 {a}^{2} \times 6 {b}^{2} + (6 {b}^{2}) {}^{2} \\ 25 {a}^{4} - 60 { a}^{2} {b}^{2} + 36 {b}^{4}$
