Question

utilizando as regras de produtos notáveis , calcule: a) ( a + b)²= b) (×+3)²= c) (7× +1 )²= d) (2× + 7)²= e) (a⁵+2bc)²=​

Answer 1

a) a² + 2ab + b²

b) x²+ 2(3)(x) + 3² = x² + 6x + 9

c) (7x)² + 2(7x)(1) + 1² = 49x² + 14x + 1

d) (2x)² + 2(2x)(7) + 7² = 4x² + 28x + 49

e) (a⁵)² + 2(a⁵)(2bc) + (2bc)² = a^10 + 4a⁵bc + 4b²c²
