Assinala as opções verdadeiras.

(2 + b) ×(2 + b) = 4 + b2\left(2\ +\ b\right)\ \times\left(2\ +\ b\right)\ =\ 4\ +\ b^2

(3x)2=x26x+9\left(3-x\right)^2=x^2-6x+9

(2a+b)2=2a2+b2+4ab\left(2a+b\right)^2=2a^2+b^2+4ab

(2+4x)2=16x2+16x+4\left(2+4x\right)^2=16x^2+16x+4

Seleciona a igualdade que não está correta.

(3x1)2=9x36x + 1\left(3x-1\right)^2=9x^3-6x\ +\ 1

(4x + 1)×(4x+1) = 16x2+8x +1\left(4x\ +\ 1\right)\times\left(4x+1\right)\ =\ 16x^2+8x\ +1

(2x1)2= 4x24x+1\left(2x-1\right)^2=\ 4x^2-4x+1

(x+1)2=x2+2x+1\left(x+1\right)^2=x^2+2x+1

Quais das afirmações abaixo estão corretas?

(ab)×(ab) = b2a2\left(a-b\right)\times\left(a-b\right)\ =\ b^2-a^2

(a+b)×(a+b)=a2+b2\left(a+b\right)\times\left(a+b\right)=a^2+b^2

(a+b)2=a2+b2+2ab\left(a+b\right)^2=a^2+b^2+2ab

(a+b)2=a2+b2+ab\left(a+b\right)^2=a^2+b^2+ab

(ab)2=a2+b22ab\left(a-b\right)^2=a^2+b^2-2ab
