Question

necesito ayuda porfis
(×+1)(×+1)
(×+4)(×+4)
(×+2)(×+3)
(×+6)(×+2)
(×+8)(×+2)​

Answer 1

Respuesta:

(x+1)(x+1) = (x+1)² = utilizas a²+2ab+b² = x²+2x+1

(x+4)(x+4)= (x+4)² = utilizas a²+2ab+b = x²+8x+16

(x+2)(x+3) = x²+3x+2x+6 = x²+5x+6

(×+6)(×+2) = x²+2x+6x+12 = x²+8x+12

(×+8)(×+2)​ = x²+2x+8x+16 = x²+10x+16

Espero te sirva :).
