Productos Notables Reduce:
*A=(x+6)²–x²–12x *B=(x+5)(x–5)+30
*C=(x+7)(x–5)+x²

Answer 1

Respuesta:

Explicación paso a paso:

A=(x+6)²–x²–12x

A = x² + 2×6x + 6² - x²–12x

A =  x² + 12x + 36 - x²–12x

A = 36

B=(x+5)(x–5)+30

B = x² - 5² + 30

B = x² - 25 + 30

B = x² + 5

C=(x+7)(x–5)+x²

C = x² + 2x - 35 + x²

C = 2x² + 2x - 35
